6 dpo

here are a few of my symptoms, a part of me doesn't want to believe that they're actually symptoms what do you think? I have diarrhea / loose stools, I've had insomnia really bad, very irritable today, and when I eat I don't really feel good. I've had a few episodes of heartburn but not very long. and a few days ago my left breast hurt really bad on the side and I never get sore boobs. I know this is probably weird but I've never really had feeling in them as far as pain goes. I'm still trying even though last time was a big devastation. but I feel like I should be having more symptoms than I have been having but I don't know why I've never been pregnant before this is my first.
