I’m unexplained. Have a 10 year old DD and have been pregnant since, about 3.5 years ago. Came off contraception and started ttc two years ago and nothing.
I had so many tests done. AMH, FSH, thyroid, progesterone, prolactin, AMH again. Pelvic scans, two 3D internal scans to check uterine lining and thickness and one 2D internal exam to check my ovarian reserve and make sure I had no cysts. And I had a hycosy which involved inflating my uterus and having dye injected in to check for scar tissue (which was my initial concern) and for blocked tubes, all done alongside another 3D scan. My partner had bloods done and had to do two semen samples (which he moaned about doing. Because apparently wanking off into a cup is SO much more difficult and traumatic than having a wand shoved up your vagina and dye squirted through your tubes).
Anyway every single thing came back totally fine and normal. Doctors and sonographers even both remarked at how lovely my lining/uterine cavity was. The fertility doctor said exactly what I was waiting for... “well you’ve been pregnant before so there’s no reason you won’t get pregnant again”. Sure, tell that to my effing useless ovaries.
So we haven’t been actively ttc for about 5 months now, as in no opks, no regimented sex etc. Just having sex when we want. You know, relaxing like everyone says to. But guess what, still no pregnancy. In a weird way, I wish they HAD found something wrong with me because it seems that most of the time, it’s something that can be helped with meds/surgery/lifestyle changes or even fixed completely. The fact that they’re nothing physically wrong with either of us and yet my reproductive system just fails every month to do the one job it’s designed to do with no actual explanation as to why, is very frustrating and something I’ve really struggled to come to terms with
