[|Human|] Hi, I have been on microgynon 30 for a number of years. Have just got back from Kenya and have been taking malarone. I was on my pill break and due to come on Friday, am regular as clockwork and have still not come on. Due to start taking pill again tonight. Did not have sex in the 2 weeks I was away as bf not with me. Came back tues night and had sex with condom but it split. Have a done a pragnancy test which was negative. Do I take my pill as normal tonight or wait for period. Also what are chances of being pregnant? Thanks, Vikki
[|AI|]  Hello, I have gone through the query and understood your concern. Any antibiotic or antibacterial agent can affect the performance of an oral contraceptive pill and cause failures. This may be applicable to the anti-malarial preparations also. Yet, I do not think you could be pregnant since you had the intercourse after your expected period. Home pregnancy tests read well when performed 3-7 days after a missed period and not earlier. You should get a blood test done to exclude/confirm pregnancy before you decide whether to continue with the pill. Hope this helps.
