Hello, ok ill get straight to the point i came off birth control a year ago my periods were always regular 28 days before going on it, was on it for several years, since coming off it my periods have gone between 29 and 34 days which i dont mind because i still have a rough idea when it will be, my last period was in november, my next one was roughly due the 18 th of december, i took a test on xmas day and got negative, ive not taking another test but will be going for bloods next week, i was just wondering if anyone has after a year just skipped a period after implanon being in, or did i catch the egg and just not know it, we have being trying, please no smart comments please, as i will be going to the doctors next week ill be finding out in there whats happening. I just wanted some opinions, do you think i could be pregnant, not under stress, no weigh gain or loss, same eating pattern, not over exercising, no drugs/medications. All advice needed please, o and headaches,back pain, tender breasts and nipples, mild strange cramps in lower abdomen.
