I have a tracker and I still had in protected sex. unfortunatlt it was AAAAAAA the first day I started birth control . could I be pregnet? [/INST] His will try my best to answer your query. It is always better to use some contraception method when you are not planning to be pregnant. Yes there is high chances of one getting pregnant if you have unprotected sex. I advise you to test yourself by using urine pregnancy test kit, follow the simple instruction on the kit and preferably use early morning sample urine to test. Hope my answer will be helpful for you. Take care. </s>
