Pregnant or period?

My boyfriend and I had sex about a week ago. We did anal, and he came in there. Nothing dripped into my vagina, but I’ve been super paranoid for the past week. I took a test, but it came back negative. I’ve been having headaches, cramps, my stomach has been gurgling all day today. I haven’t been feeling nauseous at all. I’ve been taking my birth control religiously. My period is due in 11 days according to <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a>. My period was also late last month.

Maybe I’m just being anxious and my period is coming.
