Hello well my quiestion is should i be worried or not i had unprotected sex with my boyfriend on the 21of feb.on a friday i took a plan b that night but had sex again the following day thats saturday and didnt take any pill but had my period on sunday af

Hmmmm: The bleeding you had that sunday could have been from the plan b and not your period. Two things to consider here. One is that you should check a pregnancy test. Two is that its time to see your physician about some birth control. In the situation you described, you more or less wasted the plan B by continuing to have unprotected sex. Try some condoms until you get seen.

Likely not pregnant: If the period u got on Sun was expected and of normal duration, then it is unlikely that u r pregnant. If concerned, u can check a urine pregnancy test about 2wks after last unprotected sex. While Plan B may have protected u for both days, it is not the ideal way to do so, and it is far more expensive than oral contraceptive pills which are also more effective. Please see dr to discuss options.
