I don't know what to think

At first I was certain that I could be prego but now I just don't know. I've been pregnant twice before I mc both times and both times the only thing I notice was my really sore boob's and really hard cramps. This time I'm just get pelvic twangs here and there bloated some times I'm sick I also get hot flashes/cold chills. Lower back pain,Nauseous n gagging no sore boob's and I'm like 3days away til my AF is due. IDK 😕
