I Have Baby fever!!!

So I'm 26 and I have An extreme case of baby fever! I've been wanting to get pregnant for about a year now. I want to get pregnant before I hit 30 but I've been having a hard time. I've tried prenatal pills and jelly without spermicide but still no luck. I have gotten pregnancy once before but @ 5 weeks I had a miscarriage....(sad day) is there anything else I can try for my little bundle of joy?

Also I get cramps pretty bad on my first day is that normal or is it taking away from my fertility?
