Bloating and spotting

Patient: Hello, I am on the contraceptive pill; cilest. i had normal period last month and then started my second pack of cilest after my 7 day break. 2 weeks into this pack i had unprotected sex, however i was on the contraceptive pill. The day after this i was vomiting a lot due to a alcohol. i then experienced a very light period for a week and then 4 days or nothing except slight bloating. I have now started spotting and have extreme bloating, this has been happening for about 3 days. please help?
