ok so i took a plan b exactly two weeks ago, 12 hrs after sex. This was 1 week after my period came. A week later I had strange bleeding which from what I read is normal. Yesterday I was feeling really sick and like i wanted to throw up but never did, could this still be an effect of the plan B?
In case you're confused by this everything happened on Wednesdays, period started Feb 27, sex and plan b taken march 5th, bled again the 12th, and now yesterday i felt bad in my stomach.

Is there anything more I can expect from the pills? And will my next period be on time as in at the end of this month like usual or will it be in the middle of next month?
