So I've been trying to get pregnant since December and nothing so we decided two separate. But on may 1,2,3,5,12 we saw each other on those daysI didn't think that I was going to get pregnant because we've been trying since December right... But then I get my cycle the 13 14 15 and 16... But here's the thing after that on the 24 I saw someone else right and I did have but nothing inside so in June 7 I so my ex agent but on the 13th I did a pregnancy test and it came positive they did an ultrasound no baby yet saw on the 14 I went to the emergency because they thought that the baby he was outside so I was kind of scared that was going to get an abortion but I was early I was 3 weeks or 4 weeks so right now I'm scared because I told him that I was pregnant and he told me how I know that is mine and I was like I had the same question so I need help here do you think it will be the other person either way I don't know I'm kind of confused and I don't know how it works I just need help please cuz I'm kind of scared right now I still don't see a doctor I got me an appointment for August 20th so on the calendar it they say that I'm 9 weeks but girls what do you think I think I will be sure that is my ex right but I'm kind of scared!?
