Had sex using pull out method on day11,13of cycle.he ejaculated outside washed with water,had sex again using pull out.nauseous.do i need to tk planb?

Yes if...: If you do not desire pregnancy, then you need Plan B. You are at the fertile part of your cycle, and the pull-out method is useless as a contraception. The fluids before ejaculation have plenty of sperm to get you pregnant. Then you need to see someone about a more appropriate form of contraception if you are going to remain sexually active. Plan B is emergency contraception, not for routine use.
