2nd miscarriage

[Halla]

hi everyone, I had a miscarriage on 6th of dec 00
3 months later I got pregnant again, I was very sick, I had hyperemisis and spent first 4 months in and out of hospital, but i had a beautiful little girl, now 20 months.
I got pregnant again but miscarried in April at 17 weeks. lots of blood tests were done, but no reason became apparant. In Ireland, you need to have 3 consequtive (sp) miscarriages before dna testing will be done, so they sent me home and said there was nothing they could do unless I had another 2 miscarriages.
I am planning to try again, I won't give up. but I wonder are some people's bodies not meant to be pregnant or whether it's just bad luck. any ideas on what i should do?
