Advice needed

Hi girls! I'm in need of some advice. Two weeks ago I went on holiday with my boyfriend and got very busy :p I'm on the pill but was on a two week course of antibiotics leading upto the holiday. This morning I woke up feeling really sick but didn't actually vomit. It's come and gone all day. I suffered a miscarriage at 9 weeks in April. I know know if the medication I was on can effect my pill. Can anyone offer any insights???
