Hi,I took plan b one step on dec. 7 and shortly after that on dec. 12th I got my period.  It has been almost a month since the time the period has ended and i havent gotten a second one yet.  I have taken 2 pregnancy tests and they have botChatDoctore out negative  is it possible that I could pregnant or am I just over-thinking it?
Hi, Most probably the delay in your menses is due to side effects of Plan B One Step. These medicine contains a hormone levonogestrel and the bleeding a few days after taking it was with Chat Doctor.  That is why, it is common for the next cycle to be either early or late, and the flow heavy or low. It is good that you did the pregnancy tests. Now that the tests were negative, please do not worry and wait for the regular menses to resume. Hope this is of help. Best wishes.
