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 thats 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 botChatDoctore 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

Hi, thanks for using Chat Doctor. Your period was delayed for only a day and your description of symptoms are suggestive of menstrual bleed. As you are passing clots, could be due to well-formed endometrium resulting more bleed. Not to worry. Usually urine pregnancy test shows positive results a week after missed period, Blood Chat Doctor test is more sensitive in detecting early pregnancy. Use of birth control pill helps to regularize hormonal changes in body, so makes cycles regular. Usually bleeding starts with in a week of taking last active pill. Hope this helps you Regards
