Good luck with your IVF treatment, Soapsuds, and anyone else who is trying to conceive.
I have endometriosis and I haven't wanted children so I never found out if I was fertile or not. A lot of women with endometriosis have trouble conceiving, but with treatment many women do have children. So I just wanted to pop in and mention this condition for the benefit of anyone reading this thread, as it can be hard to diagnose and treat, and this can impact on fertility.
It's something I imagine the doctors check for before starting IVF? I don't really know, tbh. A friend of mine was trying to conceive naturally and not having any luck, so I asked her about endometriosis... it turned out she did have it, and she got treatment and went on Clomid, and now has two children. I am not sure if she would have found out about it in time if I hadn't mentioned it. Many doctors are not proactive enough in considering this diagnosis, and as you will be aware, the clock is ticking. The longer endometriosis goes undiagnosed, the harder it may be to conceive.
If a woman has endometriosis, then it is usually best to have the deposits removed and any scar tissue that may be distorting the position of the pelvic organs dealt with too. After surgery there is a window of time where the chance of conceiving and having a successful pregnancy are higher. Once the deposits start growing again it can lead to scar tissue formation and the organs can stick to each other and make conception and pregnancy difficult. If there is scar tissue present it can increase discomfort and pain during pregnancy, but the woman and the baby are still healthy and things go ok.
I hope this info helps someone and if you want to know more about endometriosis please ask, and I can link you to some resources about it.
