birth control
"I have had Nexplanon for a month and a half. I have experienced spotting through out the whole time. But no other side effects. My boyfriend and I recently got a surprise that I am pregnant!!. This was such a shock considering that I have birth control. SO it is a definitely a MAJOR fail. Either my boyfriend has super sperm or I have a uterus made out of steel, but this was definitely not a great choice for me :("
