8dpo Spotting/Laparoscopy Scheduled

March 26th I had an appt to talk about doing a laparoscopy procedure to diagnose what my doctor believes to be endometriosis. I went off birth control in December to start TTC she warned me my AF pain will get much worse but if I could tough it out we will try. Sure enough, it’s been hell. Predominantly on my left side both during AF and throughout my cycle. I scheduled the procedure for April 24th. She told me to stop BD or at least have protection until the procedure. I had been doing opk testing since going off birth control in December and not a single even CLOSE to positive test. 3 days after that appointment, I randomly took an opk and it was positive!!! My husband and I talked.. and decided to try one more time. AF would still be coming before the procedure to confirm I am not pregnant prior to. If we needed to postpone it we were good with it. Let’s give this one Hail Mary! I am 8DPO and this morning had the lightest brown spotting show up only when I wipe. Hoping this is implantation bleeding. Any ladies experience this? It’s possible I’m actually 9 or 10 DPO if I missed my first positive test a day or two before my positive when I randomly tested. 🤞
