OK so in the last weekend of march I has a two day period very very light and brown a little thick, I was due for a period the first week of April so it was a little early but I wasn't worried, then in the middle of April I had another 2 day light light period again brown, and then Friday may 3rd I got another brown period that lasted two days barely very very light..I had unprotected sex using the pullout method once just before valentines day and a few times in early/mid march
