Have you had any tests done to find out why you are miscarrying?
I had at least two confirmed miscarriages (I had a D&C done with them) and I suspect a third miscarriage but I don't know for sure (REALLY REALLY HEAVY Bleeding) before I had my son. After going through all of that and close to four years of trying to have a baby I'm happy with my son. If he is all I can have I am happy for that. But at the same time I wouldn't mind having more kids but I'm in a similar spot as you are. I don't know if I can keep trying and keep trying only to have miscarriages. It takes a lot out of you. Even through my son is only 3 months old, I still want more kids and I understand how you feel. My family doesn't feel complete.
But I guess in the end it is up to you. What do you want more? If you really feel like there's this empty void in you then give it a try. I was REALLY spiteful after my first miscarriage. I knew I lost the baby before my doctors did for my second one. I remember praying to God to either let my baby be all right or to help me to move on and get past it.
My husband says he never really wanted kids but knew he'd have them because I wanted kids. He's also very happy with our son but he can't think about having more kids right now. But that he will support me.
I know after my 2 confirmed miscarriages I told him that If I didn't get pregnant and stay pregnant that I would see a genetist and see what was going on. Turns out my blood work showed some kind of inconsistency and I had to take baby aspirin every day/every other day for the first 5 months of my pregnancy to thin the blood. I also took 200mcg folic acid. And poof I had a healthy boy.
Was that what did the trick? I'd like to think so, but you never know. I guess my thinking now is: If God wants me to have another child I will. I'll do what I can to stay pregnant-like the aspirin and such but if it doesn't work, it doesn't work, and in the end I have a beautiful son.
