Hi. I am 21 years old, I have a couple questions hopefully someone can help me. I got on depo in January, I was on it for 9months, thats 3 shots. I got off of depo in october I missed my shot, I decided to get off because I had gain a great amount of weight, and the mood swings were becoming horrific, that same month when I got off depo I started another birthcontrol witch was ortho-evra. I was only on it for the a couple of weeks the end of October and November and I got off. In November 16 I got my period like I was suppose to because of the patch, I got a regular period and it ended on 21. I got my period again on the 28 and it ended on the 3rd of december. I have not gotten my period for the month of December and im not sure if I should take a pregnancy test, me and my husband are trying to have a baby but at this moment I am very confused! Has this happen to anyone or been in the similar situation? -comments & concerns will be appreciated. Thanks.
