Not sure what’s going on!

Buckle in ladies 💕😂

I got a positive ovulation test March 15th. Me and my partner did the thing the 10th, 12th, and 14th. The 19-21 I had cramps in and off, sore boobs and nausea. I was due for my period the 28th. I cramped a little but nothing has happened. I have taken tests and they are still negative. My period has always come when expected. Never late. Except when I was pregnant with my son. I always cramp and then start bleeding but other than those small cramps on the 28th I’ve had no cramps or anything.

Has anyone experienced this and been pregnant? Did you have to go get a blood test? Help!!

TIA
