I'm not expecting my period until 8/31 and I started bleeding this morning but it's only when I wipe. It's pink/red and more than what I thought "spotting" would be. I ovulated around 8/15-8/16. My periods never come early. I've take. 2 pregnancy tests and both were negative(I think I tested really early). Could this be implantation or has my period came early? Please help!! TIA!!
