TTC - Pregnancy Symptoms

Brianna
We have been TTC for about a month. We have had sex nearly every single night. My period is due February 1st. Yesterday, I had mildly tender breasts, it has continued into today. I do get tenderness before my period; however, it is accompanied by this weird feeling in my stomach. I don't really know how to explain it. It feels somewhat like gas, trapped gas sort of, it's odd, it really is. It's a very bloated/full feeling. It's not a sick feeling, just very odd and something that I haven't experienced. I have been rather sleepy, I don't usually get that. I know you all can't tell me if I'm pregnant, just hoping to hear if anyone has experienced, or can explain better this stomach feeling.
