I started birth control on January 31st. I started having a period on Thursday, February 11 and it has continued since then, even though I am supposed to be starting my period this upcoming week. It s pretty heavy flow consistently which is unusual for me. I also had sex on the 12th, 13th, and 14th. Should I be concerned or is this seemingly normal because this is my first pack of birth control? Everything I ve found online up to this point says that spotting is normal, but I haven t really found anything about an actual heavy period. Thanks!
