I recently got my second Nexplanon inserted and this time it is horrible i have gained 15 pounds in over a month, my period has been on for three weeks & i overall just feel bad. My boyfriend finished in me today (Saturday) & i am suppose to get this Nexplanon taken out Monday and get on the pill. I know sperm lives for 5 days, so is it possible i can become pregnant as soon as i get it taken out? thanks for your help <3
