I got my nexplanon implant on Monday and I’m wondering when should I expect my period?? I am breastfeeding so I know that can affect when it returns and that the nexplanon can cause irregular or non-existent periods. I haven’t had a period yet, my husband and I did have unprotected sex before my birth control (we got a little too heated one night, I know it was bad 🙃) but I took plan B the next day and he pulled out. We really aren’t trying for another baby anytime soon.
