My partner and I had sex on first day of my period, it was really light, only a little bit of clotty stuff had come out on my tampon
The day after, my period stopped, could that mean I am pregnant?

It's possible, but it is also not uncommon for women to find that their period is altered when they have sex during it or right before. You would need to wait until your next period is due and see what happens, then test at that time if necessary.
