I had only been on birth control for a week after my 6 week check up post pardon. And 2 weeks ago on Sunday my husband and I had sex and he finished. Sunday night i took the pill but Monday and Tuesday I forgot to take the pill. Do wednesday i took 2 pills and plan b. 72 hours after....but the since Sunday, I've been having break through bleeding. And I continued to bleed after plan b until the following Sunday. Just got my period on the period pills week but it's very light. So I'm unsure if I'm pregnant. Just had a baby 2 months ago and don't want another right now. Any advice?
