10 days late... Help!

Brooke

I am 22 years old and I’ve never had a period be this late. I did have unprotected sex a few times in February. 5 days after my period was supposed to arrive, I took a pregnancy test. It came out completely negative. I did take it in the afternoon, after I drank caffeine to make me go. Now I’m 10 days late and nothing. Just cramping. Should I re test? Or attribute being late to something else? I did start exercising and eating cleaner, but even when I’ve done that before it’s never really made me late. Just confused and don’t want to get my hopes up.

Thanks guys
