So i had my period on the 3rd, my cycle is ALWAYS on time, sometimes a few days early. My next period is due august 3rd. So i used opk 13th-17th, all negative. The 18th which was my predicted ovulation day, i forgot to take a test. That night i had my ewcm, which i had since the 14th, my cervix was prime. I had my sore boobs, cramping on left side only. So i didnt take anymore tests bc thats all my signs for ovulation. I was also disappointed bc my left tube is blocked, so i started preparing to do it again next month since my right tube is open. Well on the 24th i started getting cramps on my left side again, plus a few twinges on the right side. I had slight spotting, only a line of pinkish red blood. I checked my cervix and it was high but closed. I assumed possibly implantation since I've never spotted between periods before. I've still been getting little cramps on both sides until today its been mainly on my left again. So i checked my cervix and its high barely open. I decided to take an ovulation test and it showed this, which seems positive. Any one have any suggestions on what could be happening??
