I had unprotected sex 3 weeks ago (9/6) when I was fertile and took plan b two days later (9/8). I was supposed to get my period last friday (9/20), but on wednesday of last week (9/18) I started getting a very light period (I always get heavy periods) that has continued to today (9/27) more than a week, my periods last 6 days. Is this a side effect of plan b? It's not listed as one on their website
Yes, it can delay periods, lighten periods, make them more heavy. It can really mess with your cycle and it is different for every woman. Some women will take it and bleed about a week or so later then their next period is usually delayed. Some women dont bleed and their next period may be heavier or lighter. You should be back to normal next month. If you are going to be sexually active, you are better off getting regular birth control pills. They are not so hard on your system and they are more effective.
