1st round IUI success- TTC w/ endometriosis

IUI round 1 was a success, so I thought I would share my charts with you all. I have Endosalpingiosis and stage 4 endometriosis, we tried naturally for 4 years after I had the laparoscopy surgery. Heres my chart and line progression

This was our 1st cycle with IUI. I had 4 mature eggs and hubby had 1% normal sperm at the time. I did an HSG a couple months prior to unblock my left tube. Dr confirmed I ovulated from that side in this cyle. For meds, I used Letrozole at the beginning of the cycle, and Progesterone from 1dpIUI-14 weeks. My 1st BFP was at 12dpt. Symptoms started around 8dpt due to very rapid HCG. At 15dpt, HCG was at 425. Currently 31 weeks along with healthy baby girl who is 1 week ahead on all developement and measurements.💕
