So.. I had sex with a condom (nothing went wrong with it that I know of, I've known him for awhile and he is a bit weird but I definitely don't think he would take it off during or not tell me if it broke) on december 10th and got a completely normal period on december 16th - heavy, normal pms, lasted four days (which seems short but is very normal for me). According to my period tracker app I am now two days late.. I have not taken a test yet but I am going to tomorrow. There are a few things that could be affecting my cycle, like I recently started my first semester of university so that has been a little added stress and a lot of studying. I also changed my diet to lose weight (five pounds down whoo!) and have been walking a lot more to make my 10 000 steps a day. I also stopped taking yaz birth control in August and the withdrawal from that did cause a weird cycle - two weeks in between my periods in september, 28 days until the next one, another six weeks, then three and a half weeks and then three weeks so it's obviously been a little irregular, but could it still be affecting me in January? could i be pregnant? has anyone been in this situation before? hoping im just crazy!
