Was on yasmin plus pills for 2 months and stopped.started my last period on the 31st of march.finished the pack. had no withdrawal bleeding.i am a day late for my period this month.have period pains,backpain and tingly nipples.am i possibly pregnant?

Given the information supplied, wait another week and obtain a serum HCG test to be certain about pregnancy. If there may have been a delay after the seven placebo days of the "previous Yasmin pack" (not the one just finished) , there is a chance for pregnancy. In addition, the low hormonal content of Yasmin may occasionally result in minimal to no noticed withdrawal bleeding.
