Question: How will Plan B effect my period?

 dolejuice - Mon Mar 01, 2010 12:48 am

I took Plan B (consisting of only one pill, it didn't come with two) on Sunday Feb. 21st around 11 in the morning. Around Saturday Feb. 27th I started bleeding in the morning and I still am today (Sunday Feb. 28th), I got cramps and the flow is similar to my regular period, only I shouldn't be getting my period until around March 8th or 9th, seeing as how my last period was Feb. 9th.

I'm wondering if this bleeding would be considered my period for the month of March? Or if I'll get my period again when I would normally get it. And if I don't get it around March 8th or 9th could I be pregnant even though I've bled?

User avatar Hello,
Because of the high level of hormones, this often causes disruption in menses and each woman is different so we can't say when you might expect your next period. In some cases it takes several months before a routine is established again. In others, the periods resume in a pattern within a couple of months. I'm afraid it's a wait and see game at this point.

Best wishes.
