Is the blood you are experiencing period type blood or more?

It could be the result of a miscarriage or it could just be your body responding to coming off of the pill and getting back to normal. I know that when I came off the pill my period was all over the place, my period pain was much worse, I did not have any on the pill, my breasts were sore and so on, this is why I say it COULD be a normal side effect from coming off of the pill.

If it is alot of blood, more than a normal period, if there are any clots, as you would only be 3 weeks pregnant (2 weeks before you had unprotected sex and 1 week since) then you may not get any clots as it is so early. If you have really bad cramping then I would suggest that you go to see a GP or the hospital.

Do you have anyone to speak to in real life? Your Mum, older sister, friends Mum?
