I want to take 2 pill packets (microgynon 30) in a row because i don't want to be on my period over my birthday but am unable to get a doctors appointment on time to start another pack straight away - I have an old pack that i took 6 pills of and then decided i didnt need to be on the pill a while ago, can i use those remaining ones and then switch onto a new packet for the remaining 6 pills? Ill go on my period and then start a new one fresh. Pregnancy risk? Im confused. Thanks
