Hi, I ve been taking the Sprintec 28 since Sept. 2013, I started it two weeks after i had gotten my september menstral flow because i had spotting that didnt stop for two days and my doctor said i could start the Sprintec. Well i had my period for 4 weeks straight until i started the next pack. i was clear for about 3 weeks (normal) but after i finished that pack but once i started the following pack, i started to bleed again a week later. that lasted 3 weeks until the end of the pack. this had been the same pattern almost every month... what should i do?
