My period was due around the 1st-5th of this month... and still no show. Lately I've been having small stomach cramps, my breasts are slightly tender and kind of aching, missed my period obviously, nausea off and on, appetitie change, exhaustion, an increase in gas, and more urination than usual. I however have got only negative pregnancy tests. I have scheduled a appt. with my OBGYN for a blood test and everything. Do you guys think that I could be pregnant dispite the negative tests?
