Please someone help:(

Okay yes I’m one of those people that hasn’t taken a pregnancy test and is going to tell you my symptoms anyways. So I’m on birth control the implant which is 99% effective, yes I let my boyfriend finish inside me and I know the small/tiny risk I’m taking. Ive been feeling a little off lately like my boobs feel a little heavier then usual and my tummy feels weird like I don’t know how to explain it. Yes I know some of these symptoms could also be my period, but my period is irregular due to my birth control, but yes I am late. I just honestly want to know what you guys think. I just feel off and idk if anyone of you who were pregnant felt the same. Could I be pregnant? I’m also posting this anonymously because I feel ashamed:( i kinda just want someone to respond honestly idk it’s 4am and I haven’t went to sleep. I don’t know why I haven’t been able to sleep. Anyways thanks you for taking your time reading this.
