So I took plan b Jan 5th and then Jan 12th I had really heavy bleeding for 3 days and then it just stopped. I assumed that was like a "reset period" from plan b. Then on the 30th I got my period again (the regular time it should of been if I didn't take plan b) and now already on the Feb 2nd it is slowing down already it's only been 3-4 days. My periods always were the same in length and flow. Light on day 1 heavy day 2-5 and then light again 6-8. Now it is heavy day 1-2 and then light 3-4. Did plan b do this? Will it go back to normal or?
