I have been prescribed microlite as a contraceptive pill. I haven't taken it yet I am due my period around the 4th of August (in 10 days) and I start my pill then. I know I have to wait 7 days before I'm protected. I'm going away with my boyfriend on the 21st of August and I was wondering will my pill be effective as the only form of contraception for me to use or do I need to be on it longer? Thanks!
