I‘ve been on the birth control pill for about a year. Recently I got the implant (Nexplanon) I got it the 14th, the doctor forgot to tell me to take my pills for 3 days to make sure. We’ll me and my boyfriend had sex those days. My stomach has been cramping really bad, I’ve had a migraine for about a week now, been constantly tired, and not very hungry. I had bleeding for only a day, the week after I got my implant. My period is in 4 days. And I just had this..
