I had a period the 3rd of Jan only lasted 2-3 days very light. I’ve had sex over the weekend various times. (This is my ovulation week so it was right in between my fertility window. ) And again last night before my hubby left over the road. Now today , I’m feeling very crampy, almost like period cramping, I know it ain’t a period coming cuz just had one not to long ago lol , & along with lower minor back pain. It probably too soon to test , but just went to see what others think. Thanks.
