Trying for the second, and it isn't happening
It worked before, possibly without trying, and now it will not — and you are surrounded by a child who is proof it should be simple.
This has a name and a threshold and an evaluation, and almost nobody treats it that way, including the people going through it.

The rules are the same rules
NICHD defines infertility as not achieving pregnancy after one year of regular, unprotected sex — or after six months if the woman is older than thirty-five. There is no clause about previous children.
So if you are past that mark, you meet the criteria for an evaluation. Not a lesser version of one. The same tests, and the same reasoning about which partner to check — remembering NICHD's line that problems in the male are just as likely as problems in the female, which applies here too.
Time has also passed since your first. Both of you are older, and things can have changed for either of you — surgery, an infection, a new condition, a different weight or medication. A previous pregnancy is evidence about the past, not the present.
Why it is harder to say out loud
People struggling for a second describe two things nobody warns them about, and both make asking for help harder.
The first is guilt. You have a child, and wanting another can feel greedy in a way wanting the first never did — particularly around friends who have none. It is not greedy. Wanting a second child does not diminish the first one, and grief about a family that is not arriving is not conditional on having no family at all.
The second is the constant, cheerful asking. When are you giving them a sibling. Do not leave it too long. Every one of those lands somewhere, and the person asking has no idea. You are allowed to answer briefly and change the subject, and you are allowed to tell one or two people the truth so that you are not carrying it alone.
There is also a practical isolation. Support groups and clinics are often oriented around a first pregnancy, and appointments are harder to attend when you already have a child to arrange care for.
When someone tells you to relax
This is the single most common thing people in this situation are told, and it is worth knowing it is not an assessment.
It is usually offered kindly, by people who have run out of anything else to say. It nonetheless does two unhelpful things: it implies you are the cause, and it substitutes reassurance for the evaluation you actually came for.
If it comes from a clinician, it is reasonable to ask directly what tests would be indicated given how long you have been trying and your age. Ask for the plan rather than the reassurance.
The same applies to unexplained results. Being told there is no identified cause is a finding, not a dismissal — and it is a common one. It does not mean nothing can be done, and it does not mean it was your stress.
What to do next
Count honestly from when you started trying, not from when you started worrying. Those are usually months apart and the first is the one that counts.
Book if you are past the threshold for your age — a year, or six months over thirty-five.
Ask for both partners to be assessed from the start, for the same reason as the first time round: the simplest test is the one most often deferred.
Mention anything that has changed since your first pregnancy, including how that birth went. It is directly relevant and easy to leave out because it feels like old news.
Common questions
- Do we really qualify if we already have a child?
- Yes. The definition turns on how long you have been trying and your age, not on whether you have conceived before. A year, or six months over thirty-five. Previous children do not appear in it.
- It was so easy the first time. How can something be wrong now?
- Time has passed and both of you have changed — age alone shifts things, and so can surgery, infection, weight, medication or a new condition in either partner. A previous pregnancy tells you about then, not now.
- Is it wrong to be this upset when we already have one?
- No. Wanting a second child does not take anything away from the first, and the grief of a family that is not arriving is real regardless of how many children are already in it. Feeling guilty about it is extremely common and is not evidence you are wrong to feel it.
- My doctor told me to relax. What do I say?
- Ask for the plan rather than the reassurance: given how long we have been trying and my age, what tests would you recommend, and if none, why not. That reframes it from how you are feeling to what is indicated — and if you cannot get an answer, asking for a referral is reasonable.
If it's this, not that
Still not sure
This page is the general answer. Yours is a specific child.
The advisor can be. It has read everything here, and it knows how old your children actually are — which is the whole difference wherever guidance changes with age. Ask it anything.
- She's got a temperature of 100. Is that something to worry about?
- He's obsessed with space and galaxies — what toys are worth getting him?
Free. It comes with the note.
It answers from the same cited pages you are reading, and when the question is where to go, from the real clinician, hospital and childcare records behind this site — not a link to go search them yourself. It says so when we have not written about something, and it is not a doctor; for anything urgent it gives you the threshold and tells you to call.
