This month I was supposed to get my period again on the 17th or 18th, I am only like 3 days late, I took an electronic E.P.T test and it said "not pregnant" but my period still hasn't come. Could I be pregnant? Or could the plan B pills just have affected my cycle?

You are doing the right thing by having a pregnancy test. The EPT is saying "not pregnant" but you may want to see your doctor just in case.

I would suggest using better protection or not having sex if you are taking multiple plan B pills in a month.

I have been using a spermicidal jelly called "Gynol II" extra strength and he also pulls out too...
Don't understand why my period came twice last month, could it be that I'm not pregnant but just that the plan be is messing with my cycle?
