I’m four weeks pregnant and really scared it is not right, ectopic?

Ok sorry for all the parnoia post but I just found out I was preg and kind of knew it before I even tested. I have been pregnant once before but I had an abortion at a younger age. Still sad by that I have been going nuts with what ifs because I plan on having this baby. I was pretty much disowned by my family if I didn't have the procedure and am not telling them for fear of them trying to influence me because I am only engaged to be married. Anyway I should be about four weeks and sense something is not right. I hope I'm just paranoid but at the time of conception I was using a peroxide douche because I thought I had vaginosis. I know I did this after sex as well as I wasn't planning on conceiving. Now I'm reading douching causes tubal pregnancies and for the past week I have been having cramps which come and go but they almost bring tears to my eyes and last week I had a cramp in the middle of the night that woke me up but i believe that was implantation. I have an ultrasound scheduled in two weeks but I'm so scared because of the coughing it could have interrupted the sperm on going where they need to be. Can someone enlighten me on this? The cramps are constant but enough to get me to stop mid conversation to say ouch.
