I have had Implanon for about 2 years now and I had sex about a month ago. Last year my period stopped in February and I had it again in January this year as well as february, however, I had sex February 23rd and I haven't gotten my period again. I know that not having a period is normal with this birth control but I have gained a little bit of weight and I had one day of spotting. I have not had any morning sickness, breast sensitivity, and little to know pains. Is it common to be pregnant with this birth control? Or am I just freaking out over nothing.
