Secondary infertility?

[PaleGreenAndBrightOrange]

I gave birth nearly 3 years ago to a baby that I conceived naturally (she was a surprise).

I’ve now been TTC since September. First month or two I just thought I’d get pregnant without doing anything special (apart from the obvious), then by December I thought I had better pay attention to the dates, in Jan I upgraded to OPKs but was using them wrong and in Feb decided to start using the instructions.

I know it’s taken me a while to get the whole OPK thing right by I have been having sex the whole time (though I’m sure on the wrong dates sometimes) so I’m really stressed that I’m not pregnant and as a catastrophising type of person I am convinced that my partner has cheated on me, given me chlamydia since my DD was born and I am now infertile. I have no reason to believe he has cheated on me, don’t really have trust issues and only started worrying about this because my body is refusing to get pregnant. But now that the thought has buried its way in, I’m convinced that I’m infertile and am about to lose all hope of having a 2nd child AND my marriage is going to fall apart because of this (imagined) affair.

I know this sounds insane. I guess I’m here for advice/reassurance. Has anyone else been convinced they were infertile on their 2nd baby and gone onto conceive?

How common is infertility related to chlamydia? Could it develop in 3 years?

Does anyone have a fertility centre in the london area that they recommend to look into my fertility?

Thanks in advance - sorry if this is a bit rambling

Okay, deeeeeeep breath.

1. it is completely normal to take a year to conceive, without any issues on either side.
2. you could always get a sexual health screening if you are concerned about STIs.
3. chlamydia only leads to infertility over a long time

How old are you? Are you and your partner both in good health, good weight, active etc?

Thank you for replying - I know, I’m really overthinking. I really do need to take a deep breath.

I’m 33 years old, partner and I both healthy, not overweight, active (though less so than pre lockdown, but still probably about average). I don’t smoke but my partner uses a vape.

I can’t seem to get sexual health screening because of covid, as the services (at least in my area) aren’t running at the moment. I’ve ordered a home testing kit from a pharmacy though.

I think I was tested for chlamydia last in 2018 or perhaps 2017 and it was negative. Is that not long enough?
