LADIES ASSISTANCE PLEASE

Irdk what's going on and I just want to get more opinions ... I had sex on the 17th (ov day was the 15th) and on Friday the 26th I went to the bathroom in the morning and I was bleeding. It wasn't light but it wasn't as heavy as my period. So I checked again and nothing. Kept checking all day and nothing until that night I bled again. Checked again and nothing and there's been nothing since Friday night... I've been feeling kind of bloated for about a week or so... I've also been kind of crampy w very minor lower back pain. My periods are always regular ALWAYS and I'm not supposed to get it until tomorrow that's why this is abnormal for me. I took a 99 cent store test on the night of the 26th and it was neg. could I possibly be pregnant and it was too early or I'm tripping??? Lol please help me am loling but really miserable HELP😩😩😩 baby dust to all 👏🏽👏🏽👏🏽✨💜💜
