I stared my cycle late Friday night (1/2/15) and I remember when I asked my doctor when I could start and she said on Sunday, after your cycle has came. My thing is that on the fourth week, it is saying that my period should be happening again, but that would be at the end of the month, and I usually get mines at the beginning of the month. If I start this Sunday, will I be doing it right thing or should I wait until my cycle is done?
