3 miscarriages last year and worried about future.

Jessica
So last year I had three miscarriages, one was on my boyfriends birthday which was really upsetting and I cried so much. Well the last one was November and after that I gave up trying as I was going on holidays in the December. I was referred to a gynaecologist because of the mcs and he is doing a investigation. I was told I have low protein c and after reading loads of articles that is related to mcs. Well my cycles have been weirs, first one was 37 days (only because I was put on blood thinners for breaking my ankle would of been longer otherwise) next was 35 and most recent was 31. I'm testing for ovulation this cycle but no positives yet (not even a little bit CD12.) I'm just wondering what can I do to better my chances of having a sticky baby and has anyone had a protein c deficiency and had a somewhat normal pregnancy? We've been trying for a year and I'm just scared to go through that pain again! Any advice would be brilliant!
