Period or something else?

Kayla

So I started my period four days ago and the third day I stopped bleeding completely. Mind you, my partner and I have frequent unprotected sex and he never pulls out. We had sex on my second day of having my period and again he didn’t pull out. The next day (two days ago) I stopped bleeding ENTIRELY and stopped having painful cramps and instead started having lighter, more phantom-like cramps. Yesterday It was the same, only I started bleeding again later that day so I put a tampon in. My bleeding is now lighter. I don’t have bad cramps though so this feels unusual, it doesn’t feel like I’m on my period. My partner and I have sex at least 4 times a week, if not more, and he never pulls out. What do you guys think?
