Pregnant?

C

So my bf and I had sex about 3 weeks ago when I was early in my fertile window, so I don’t think I had ovulated yet. It was his first time but not mine. We used a condom (I seriously doubt it broke) and he didn’t cum inside me at all. Of course, there’s always the threat of precum, but in theory the condom would take care of that. However, my period is now a day late according to <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a>, but my last period came like 3-5 or so days early, so idk if that could affect this period. I’ve been getting my signature PMS symptoms (bad cramps although they haven’t been as frequent lately, bloating, and extremely sensitive breasts). Even then, I’m still worried about being pregnant. I’ve never been this paranoid about getting pregnant before, but I guess I just have a feeling. My boyfriend doesn’t think I am, but he’s told me that even if I was, he wouldn’t leave me. What do y’all think?
