BFP after almost 3 years

Reanna • 34. First pregnancy. TTC for about 2.5 years. So happy!
I was diagnosed with Endo in my early 20's due to very dramatic painful periods (vomiting, fainting). When I got married we went for a pre-conception doc visit and they told me I had pros based on my lh/fsh ratio and ultrasound. I was still on the pill at the time (to control my pain). I got off the pill, started tracking, drank herbal teas, did the a paleo type low glycemic diet thing for a while, inositol, vitex, etc, etc. Got tested again and they found no sign of pcos. Don't know if it was a misdiagnosis but I still wasn't pregnant. The first year went by. I felt a little calmer, finally started tells people we were trying, got support from friends and family. Read the books, tried various natural health care people, got blood tests, etc. Long story short, in the last few months I stopped doing other people's programs. Started chasing info on the thing I knew was wrong, which is my painful periods (membranous dysmenorrhea, causing vasovagal syncope). A midwife friend said it sounded like low progesterone. My blood levels were good on two lab tests, but a couple midwives told me that might not be the whole story. So I finally bought the progesterone cream to see if it would help my periods. 
Had very clumpy brown spotting days 8, 9 and 10. Figured I was out of the game. Continued the progesterone cream to 14 dpo anyway, just to see if I could make my lp longer. Started cramping , but no blood. Didn't want to take my usual painkiller until I saw real blood or a negative test, just in case. Sent hubs out for a test. Peed in a mug while I waited for him to return. Imagine my surprise! Started shaking an crying when I realized there was a second line!
It's early days, of course, but this is the first time I've ever been pregnant (at 34) so feels like a major breakthrough. 
I really want to see some mass studies done on TTC women based on menstrual cycle symptoms. There's so much we can learn about why we're not eating pg by observing our cycles and our health, but there's not enough data out there to know how to interpret it well. Doctors don't know much about what a healthy cycle should be, so they can't really help with that aspect. I told my gyn about the membranous dysmenorrhea and she said it was nothing. Instead they want to do a lap for Endo, but I don't even think I have Endo anymore. 
anyway, end rant. I know bfp stories made me feel hopeful, so just wanted to share. Stay strong!
