Those are some of the things I've been experiencing for a few days now. I haven't thrown up or anything, but I instantly got an upset stomach as soon as my head started hurting. I just ate a lot of food it seems as though there's a slight increase in my appetite. Also for the past week my breasts have been somewhat fuller than normal. Are these signs of pregnancy?
I am sexually active with my current boyfriend, and we do not use a condom but practice the pull-out method. I have PCOS and haven't had a period in a while.
