I'm 15 and I got the implant in February gone and my periods were fine. My periods didn't get worse as people told me they were going to, they got better. Before I got the implant my periods were quite irregular and heavy but ever since I got the implant my periods seem to come once every 3-4 weeks and I'm only on for two days - light. But I was thinking lately, I couldn't remember when my last period took place and when I thought about it properly I hadn't had a period in about 2 months. So I weighed up the possibilities and took a pregnancy test. The test came back negative. I didn't take the test at the sexual health clinic,I bought and took one at home. I've been told by numerous amounts of people to go to the clinic and take a test there, as they're more reliable. I have been getting headaches quite frequently because my mind's been working over time and my boobs seem to have got bigger and are hurting a lot of the time. It may just be me reading into the situation too much but could I be pregnant?
