im 21 and my bf and i are ttc last month i followed the ovulation cycle and did the bd during my most fertile days and the day of and the next couple of days. i had some symptoms of pregnancy but then i got what i thought to be my period(it was very unusual for me ). i continue to have the symptoms the cramping the headaches, the dizzy spells, and that feeling of i am. took several hpt's and got what looked like a faint positive so i finally went and got a digi it was negative. then this month i was early but it was very very strange i spotted the start and the next day it was a ligt flow then the next and last day it went away, i never have had a short cycle except when i took the morning after pill quite some time ago( periods have become regular until now). ive gained some weight but not enough to change clothing size but just to where my clothes fit a little snugger. took a nother hpt test and was again negative. but here's the kicker that feeling hasnt gone away and my bf even has it to. when i was pregnant with my son i got pregnant on my period and had a period so i guess my question is ...is this going to be my pregnncy trend if i am pregnant. its important for me to know for absolutly sure because i get diabeties when im pregnant so the sooner the better. thanks.
