I assume you are sure you weren't pregnant (already) on the 24th, 25th, 26th and 28th?
It sounds like you should have your ob/gyn recommend you to an endocrinologist for some clearer workups about things like cysts on ovaries and breasts, and endometriosis. You know that endometriosis can be removed surgically, right? But you have to have a good doc for that -- in our town, the IVF specialist was also the best for endometriosis removal.
If you have a heart condition, have you been cleared to try to get pregnant? It's safe?
In your shoes, along with talking to a specialist about hormonal issues and a heart doc, I would also make it a top priority to see someone about your anxiety. A lot of the physical issues you're naming could come from (or be increased by) anxiety.
I have to ask why the syringe . :)) That's like from the movies back in the 80's I honestly don't know anyone who does that unless they never talk about it. It takes the average couple a year to conceive. It took me a few years. I would definitely get some doctor input. If you have issues like polycystic ovaries, you may need some mediation. Is there a reason you are using a syringe rather than having sex? I get it, I found TTC a bit like a job. But it might be best to go that route. Also, how far up do you place the syringe? Was it sterilized each time? And my doctor says to have sex EVERY OTHER day to conceive. So, I threw a lot at you. :>) Sorry. When you have intercourse, do you have a reaction or just through the syringe?
I had endometriosis, polyps, and cysts on the ovaries removed in the past via surgery. I had spotting in between periods, and that’s when they recommended surgery. They basically performed a D&C (like when women have abortions, scraping of the lining), and laparoscopic surgery. After the surgery they put me on birth control pills and I haven’t had any issues since. Birth control pills prevent endometriosis and cysts. Yet, I know you are trying to get pregnant right now, so I’m sure you aren’t taking birth control. If endometriosis is causing you issues, and it can prevent pregnancy in some women, you need to have surgery to remove it. Also, there are treatments you should consider such as IVF instead of him inserting his sperm in you through a tube. That could have caused an infection if it wasn’t sterile. Don’t do anything like that from home, you need to go to a doctor for any type of fertilization treatments. Also, if you are having an infection that you don’t recognize, it won’t hurt for you to screen for STI’s, BV, UTI’s etc. Just as a precaution for yourself.
