My last period was four days late and then I finally got it its been 17 days and I have been feeling nauseas every now and then... my lower back hasn't really been hurting but gets kind of stiff... last two days I had period like cramps which is weird because I don't cramp not even on my period and my lower stomach has been having an aching and sometimes shooting pain but nothing unbearable and doesn't last long and I have been peeing every hour and eating so much no really hungry just constantly thinking of food my boyfriend says my boobs look bigger I think that's everything could I be pregnant I thought this before but I didn't have these many symptoms oh and plus excess saliva which sometimes when I taste it I feel nauseas and so so bloated and tons of gas what is wrong with me if I am not ?
