Why aren't I falling pregnant?

[CheeseSammich]

We're nearing the year mark ttc and still no luck. For some background I'm 24, partner is 23, a few years back I conceived after having sex once (with same partner) we weren't trying and it was a partial molar pregnancy meaning two of his sperm fertilised one of my eggs resulting in an abnormal pregnancy. I miscarried but due to some of the pregnancy not passing I started haemorrhaging and had to have a d&c two months later.
Fast forward a few years and we're not falling pregnant at all.
I'm ovulating regularly, partners sperm is fine, my hormones are fine, we eat very healthily, we're both young, my family all have great fertility and were all able to get pregnant straight away, as was I before my previous pregnancy. My periods are considered regular but vary by 1-5 days. We have sex very regularly during fertile window, I'm tracking using OPKs, BBT and CM. We have tried SMEP, Preseed, supplements etc etc.

All I can think is that I have scarring from the d&c. Other than this I have had no pelvic surgery and nothing that could have caused scarring in the reproductive system. How likely do you think it is that this may have caused scarring that prevents implantation or has blocked the fallopian tubes? Any thoughts would be really appreciated. TIA xx

Damage from a D&C is referred to as Ashermans syndrome. It is rare and would usually present with abnormally painful periods. From your op it doesn't sound like your cycle has changed particularly, and your pain level hasn't changed? Fluctuations in length seem ok, are they typically around the 25-35 days or are they particularly long/short?

Do you or DP have children from other relationships? Once you've been trying for a year, the NHS will undergo fertility testing, starting with your CD21 and a sperm analysis. Secondary infertility can be a thing, and while you didn't end up with a baby, the fact you got pregnant before doesn't necessarily mean you'll get pregnant fine the next time unfortunately.

@CheeseSammich hi. Sorry things are moving slowly for you. It can be a really stressful and time consuming process. You should approach the NHS as you are at the one year mark but don't be surprised if because of your age, they suggest you keep trying for a while longer.

Keep an open mind as there are lots of reasons that things might not be falling into place for you. However, I would say that I have just had surgery for Ashermans following an ERPC and I didn't have painful periods. After my first ERPC, periods were VERY light. I was told how rare it was and went private for treatment. Due to its rarity, I don't know if that was Asherman's or not but after the 2nd ERPC (which I only had because I was told how my issue COULDN'T be Asherman's), I didn't have any periods at all. The NHS still wouldn't help me.

So, my advice to you is know that you have time on your side, keep an open mind but do your research and advocate for yourself.

@PlanBea thank you so much for replying. My periods used to actually be severely painful from around age 14 up to when I had the d&c. They're only rarely painful now but I tend to cramp from ovulation until AF and have a very regular but mild pain in my ovaries. They're possibly slightly lighter now but couldn't say for sure. My cycles vary between 28 and 34 days but are considered regular and I know I am ovulating every month. They last around 4 to 5 days, occasionally only lasting 3 days with only 1-2 days med flow which never happened pre pregnancy. I would say my periods are completely normal for me.

No children from other relationships, we've just started testing fertility and I've had ovulation and hormone tests done and partner has had semen analysis which is all normal xx

@zoomies1 thank you for taking the time to reply. I've researched on Ashermans syndrome and based on my cycles I wouldn't say I have it. They seem completely normal, it's just the only reason I can think as to why it hasn't happened yet. But have read that some people don't show symptoms of it at all.
I'm so sorry you weren't getting the help you needed. These things really need to be taken more seriously. I hope things fall into place for you xx
