Hi. I am going on holiday on Tuesday. I am currently taking the Microgynon 30 pill. I messed up on my previous pack and missed to pills, so I had a period that lasted around 2 weeks. When that pack was finished I went straight on to take the next packet as the info said too. I have a week until this pack finishes but I have a really bad tummy ache and feel like I am going to have a period. I don't want one as I said I am going away on Tuesday. Am I likely to come on!?
