I m worried that I am pregnant. I have a regular cycle every month. My last period started on December 28th or 29th, 2010. I am not on any birth control as I do not regularly have sex. I had sex late Dec 31/early Jan 1, 2011, with the 31st being the last day of my period. I usually only bleed 3-4 days out of the month. He came inside of me. I had a fertile discharge around the 9th of January and assumed I was ovulating with the discharge being of an almost egg white consistency. On the 16th, my breasts got really tender until the 18th and they have not been tender since. Last night, on the 19th, I had some minor cramping, not even cramping really, just a weird feeling in my lower stomach. I dont know what to think. I wonder if I am pregnant or just stressing out and my body is reacting to the stress. Do you have any thoughts?
