Period cramps? #2 cramps? Pregnancy Cramps?

Been hoping I’m pregnant. I’m supposed to start my period tomorrow, but sometimes it does come a day early or late. This Morning I woke up with realllyy bad cramps, I got really upset because I thought I was about to start my period. Because that’s how it usually starts. I wake up with really bad cramps and then within a couple hours I start. But when I got to work I took some ibuprofen and went to the bathroom (sorry tmi) and took a big #2 lol. And I haven’t started my period or cramped like that all day. I have had little cramps here in there, but my period cramps are usually insane. I think I’m going to go ahead and test tonight, but I was just wondering, What’s been your experiences with cramps before your BFP?
