Okay guys I'm freaking out and need help๐Ÿ˜“ I'll be 19 in two weeks and my period is a week late. I had for last month so yesterday I took 3 pregnancy tests and they all said positive. I'm very scared and worried and so is my boyfriend and I want to go to a doctor to get a test done to make sure I am 100% positive I'm pregnant but I don't know where to go and I need help. I'm very nervous and don't know how to tell my mom but I want her to be there and help me figure this out on where to go. She had my sister at 19 and me at 21 but I'm very scared she will be mad. HELP!! ๐Ÿ˜ž๐Ÿ˜ž๐Ÿ˜ž
