BFP (sorry for the length)

About 5 months ago I had an ectopic pregnancy, really heart breaking to tell everyone that I had already told. I got the shots, it worked and was back on birth control for 3 months. December I was able to stop taking it. Husband and I baby danced on christmas because it was also ovulation day and I was supposed to get my period on Jan 9th. When it didnt come I wasnt to shocked because I have never been regular. Took some cheapy test and since it was with blue dye it was kinda of hard to tell. Tested again today and it showed a clear line, faint, but there. So I bought one of the digital ones because they are easier to read and it said pregnant. So long story short (a bit too late I know) am I being paranoid to feel afraid the ectopic might be happening again? Last time about a week before I found out I had really bad back pain for a few days, and this time I don't. I know the chances of it happening again are there, but it was heart breaking. My husband says take it day by day and we will see, but I'm the person who gets nervous fast. Just kinda need encouragement that my brain is wrong and its not happening again.
