Ovulation again?!

So I was set to ovulate on the 12th (which was my hubbys bday, making the baby due on June 4th which is my bday if I had gotten pregnant that day 😭) and instead of waking up to a positive opk, I got a period instead! It wasn’t my normal and was super light, I thought maybe it was implantation but I’ve took 2 preggo tests since then and both BFN. Glow has pushed my ovulation day back to the 2nd, so now it appears I will ovulate twice this month?? Ugh. So confused. Anyone else have this happen?? Trying for Baby #2 for about 6 months now.
