I am having my period 2 times a month- 1st when my roommate is on her period and 2nd when I should be on mine- and generally spotting in the week between....I am on my last week of a birth control pack and I am wondering if I should wait to start my next pack on the Sunday following the period I have at the same time as my roommate to try and get NY body synced so I don't continue to have 2 periods- is that ok?
