Had the implanon inserted the 5th of December..Doctors orders were to use a backup barrier for the next 7 days after the insertion of the implanon; however my boyfriend and I had unprotected sex two days after the 7 days she order and we kept on having unprotected sex before the 7days. It's been about 3 weeks since then and I'm worried my chances of pregnancy are high. I just started to spot/bleed light red on the 24th; Light lower abdominal pain. During the last two weeks I've been peeing a lot, had minor nausea, I feel bloated. When I feel hungry and eat a normal healthy food; after 4 bites I feel full but I crave sweets; specially coke. Could I be pregnant or is it just the side effects of the implant?
