I got off nexplanon on Sept 5th. Had unprotected sex on the 8th. For 4 days I have felt off. Severe nausea, lower abdominal discomfort, lower back pain, white discharge, and sore breasts. I’ve read hormone changes from getting off birth control can give similar symptoms to pregnancy. So I was seeing how common it really is to have weird symptoms after bc, or if I might be pregnant.
