I took plan B immediately after my boyfriend ejaculated inside of me, and 1 day later, I experienced light spotting which turned into a heavier flow for just under a week. It s been two weeks since I have taken the pill, and I am now suffering from mild to extreme nausea, shortness of breath, extremely sore breasts, and bloatedness. I took a pregnancy test yesterday, which came out negative. When should I take a pregnancy test again, considering my period the day after plan B was 3 weeks early?
