Period, pregnant or tripping ?

So I’ve skipped a couple periods but for these last two months I’ve been getting them I got my period a day early but I’m use to heavier periods. So I got this period and on the first day it was brown mixed with blood on the pad but then I stopped that day then I was bleeding again but my periods usually last like 5 days this time it was light and like 3-4ish days but I’ve recently changed to a healthy diet and I’ve been exercising and drinking tons of water but on the 25th my bf put half of his tip in on accident and that’s the closest I’ve been to having sex so could I be pregnant or am I just tripping? I was also ovulating that week 🤦🏾‍♀️pleaseee hellpppp!!!!!

Update: so I’m lightly bleeding again it’s brown mixed with blood so could my period be trying to come on again I been feeling a little crampy today !
