I am a 19 year old girl. I have been on the Microgynon 30 pill for coming up to 7 months now, I have just finished one set of pills, had sex for the first time last night. After which there was a lot of blood on the sheets and I am starting to get paranoid about whether or not I could be pregnant, can you help me please, I don t know what to do and I really don t want to have a baby at this time.
