Okay so on Feburary 16 my boyfriend came inside me. The next day February 17, I took Plan B pill. This was 18 hours later. Then 5 days after taking the pill I had light bleeding then it got heavyer, this lasted 5 days. So my "period" lasted from 22nd-26. I'm missed my period already. Could it be from the pill? Could I be pregnant? What's going on??? HELP!!!
Common side effects of Plan-B include your next SEVERAL periods being early or late and heavier or lighter than normal.
It is unlikely that you are pregnant, but not impossible, given when you took the pill.
Hope it helps.
