Missed period??

Paige

Ok ladies I need some input. My doctors decided to put me on birth control to try to regulate my hormones since I have such a bad imbalance. So I started taking the pill beginning of February. I only ended up actually taking it for about 2 weeks, half because I had a hard time remembering to take it and half because in those 2 weeks I gained 4 pounds. I am getting married in about a year and a half and don’t want to gain a bunch of weight. Anyways my question is, could taking the pill for 2 weeks and then stopping cause me to miss my period? According to the app I am now 12 days late. And yes my fiancé and I have unprotected sex as we both like the idea of having another baby so we aren’t actively trying to prevent it. So I know pregnancy is a possibility but I took a test at 7 days late and it was negative. Could I just be late from the birth control?
