Can I get someone's opinion please?

I already have a child but I do know that EVERY pregnancy is different. With my 1st child, I noticed something was off because I was 2 weeks late & my boobs were killing me. My 2nd pregnancy, I was a few days late but once again, my boobs were hurting really bad. Unfortunately, I miscarried at 8 weeks & 4 days. Idk if I'm pregnant yet, a week ago I was spotting that lasted a couple of hours, a week after I had my period that is. Then a couple of days later after that, I was cramping so bad it took the breath out of me. But it wasn't any where near my period at that time. Now for the past few days my boobs, again, have been killing me. The other day in the shower I noticed there was bumps on my nipples & my nipples looked swollen. I have a feeling I'm pregnant but I don't wanna be worried if I am or not just because of only being almost a day late because I was suppose to start today. I also don't wanna get my fiances hopes up he's wanting another child really bad but we're also really scared because of the miscarriage we had. Any opinions or thoughts?
