Am I in the early stages?

Ok ladies! So I started feeling like almost pulled muscle pains in my lower abdomen yesterday and I still feel them today. When I was working out earlier doing sit ups, I felt just a tiny bit of cramping and then it went away. And my boobs do feel a little tender and kinda swollen and i feel a little bloated right now. I had my period last week but it was kinda weird. (TMI) It mostly looked like brown discharge and a little like pink. No clotting and I don’t think there was any dark red. It lasted for about 4ish days and then it ended like 2 days early which is SUPER weird for me. I haven’t taken a test yet because all of this just started and I’m scared it’ll say not pregnant because I REALLY want to be pregnant! I just need some advice because I have never been pregnant before (obvi) so I want to know what all y’all think of this!!!
