I’ve recently had hormonal changes. I’m on the birth control nexplanon and I’ve been on it for about 9 months. I went through normal symtom in the beginning and got past them but suddenly I’m getting wierd symptoms like breast pain, my acne has gotten better, and slight weight gain (though my diet has not been very good) I am also sexually active. And we have used condoms and he has never cum inside Is it normal to have these symptoms after being so long on birth control or could I be pregnant?
