Pregnant or nah???

So as of right now I’m 9 days late and have been getting light cramps and having some back pain as well as nausea (all of which I get on my period). I don’t think I’ve ever been this late in my life and I’m definitely worried about being pregnant. However, I had a full period starting on the 25th of May and have had no sexual activity since the 17th of May. In the last two-ish months, I started a brand new high stress internship, turned 21 and started drinking more, and had a really bad fall. I was climbing over the back of a chair and my foot slipped. We are talking vagina straight into the back of that chair and barely being able to walk after. I was numb and bruised and swollen for a week or two after that. 😅 I’m planning on taking a test in a few days, but I’m thinking all of that pushed back my ovulation?? I keep thinking I started and running to the bathroom, but I’m stressing really hard. I’m about to graduate college in a semester with an engineering degree so a baby is the last thing my boyfriend and I need right now. Any advice or reassurance? Help a girl out 😶😶😶

Update: negative pregnancy test today! Now just the waiting game of hoping my period shows back up 🙃
