I have been on birth control to regulate my period, but my dr. was a week late to fill my prescription, I had ended up having unprotected sex on December 10 ive been having sore breasts and that's about the only difference I notice in my body, I was suppose to start my period on Jan 2 and I never got it. I took 2 home pregnancy tests and they both came up negative .I woke up this morning Jan 3 and went to the bathroom and notice some blood on my underwear so I put a pad on. The next time I went to the restroom I noticed there was hardly any blood on my pad, but as soon as I would go to the restroom blood would come out . Ive had cramps all day, but no new blood on my pad, until I actually sit on the toilet and go number 1 or two it comes out, and now Its coming out like more chunky but only when I go to the restroom. is this my period, or could I possibly be pregnant? or can it be due to me having to start my birthcontrol pills about a week later then I was suppose to have them ? please help And sorry if its to much information . Please get back to me asap thank you for your time
