How many is too many?

[cutiels1125]

I am a 26 yr old mother of one toddler boy who just turned 3 this past weekend. I have had 3 pregnancies in totaled and only survived one out of the three. The other two were really bad HG pregnancies in which I had to abort. I always read and read about people who post there losses here on this forum and I know how hard is it to deal with having to make the decision of aborting the life of a very wanted child. I'm very afraid to become pregnant but my husband wants more children so he keep me positive thinking that maybe it wont be so bad the next time around. My question is this, how many is to many abortions? I know I shouldn't be thinking this way because I should just stay positive but I want another child and I want to try to get pregnant but what if its to horrible the HG and I cant continue with the pg? Like I said I've already had two other abortions before and I'm scared to death of getting terribly sick especially because I have a 3 year old and no family close to me that can help me. What is the advise that anyone would give me!
