Big scare!

I got my tubes tied with my last pregnancy. It was a fight because I am so young. We have 4 kids very close in age and I knew I didn't want anymore children. Its been almost 8 months since I had this done. My period has been on time every single month. This month I was 2 weeks late it scared me, really bad! I took a HPT and 2 came back pos and 2 came back neg. The 2 that where neg were digi and the 2 pos were walmart brand. I went to the doctor and come to find out things like that happen to some people after having their tubed tied. Wow did I ever feel like a tard! I'm happy more then ever that I'm pregnant. I had talked to DH and he said if by chance I was he wanted to keep it. Umm hello husband you wont have to take care of it I will! I got my tubed tied for a reason and that was because I didn't want anymore children. I had it in my head I wanted to give it up. We can't afford it nor can I handle it. Right now we are living "comfortable" and another child just wouldn't work. It would have been slim it I was pregnant that it would have ended anyways. I personally wouldn't want to keep a child I KNEW I couldn't give it what it needed. My whole family was in an uproar about the whole thing. All you need to do it love it and that will work. No it wouldn't! I had 6 brothers and sister and we lived a very poor life. Living with with people, in motels and where ever anyone would let us stay. I never was able to go to the doctor or anything.. If I got sick I was told to "deal with it you can handle it!" I know being military we wouldn't have to worry about them seeing doctors and all. But we wouldn't be living as comfortable as we are now. But in the end all turned out well and I am so thankful!
