Mayb this is a good sign


I need help. I'm try for a baby my ovulation week is Aug 26th through today Sep 1st. I had unprotected intercource the 26th 30th and last night the 1st at like 1:30am. My ovulation day was the 31st today I have had a lot of cramping on the left said sharp little pains that come and go. I know to early to be pregnancy but any idea what could have be happening? I am thinking maybe my egg releasing or something but I'm lost

Update: also last night the 1st when we had sex we used the preseed line that is suppose to help get you pregnant
