hi me and my boyfriend had unprotected sex last Sunday the 19th and he pulled out but I do understand that he could have had Precum I took Plan B the next day and now it is Friday the 24th my CM is very thick and not like usual and I'm just really worried. I have an appointment with my gynecologist next Tuesday August 4th to talk to her about getting Nexplanon. I have irregular periods but my last period was June 25 and it lasted until July 1. I know that I'm not very smart and should've used A birth control in the first place but I really need help this is greatly appreciated.
