I had stopped using pills recently. After I got my period that last for 3 days I am now having brown discharge and I fell vomiting everyday and headache also occur. Could I be pregnant?

Did you have unprotected sex AFTER you stopped taking birth control?

We need to know time frames.

We did have sex on the 3rd day of the 7 days rest period of taking pills. After that I missed my period for 3 days, when I already got my period, it is not the my usual, it is lesser than the usual and it end for 3 days and since then I am having brown discharge, but the feeling that I always want to vomit that I felt before I had my period still continues until now.
