Blood testing

So last week I had my second miscarriage this year. Still hoping to conceive and carry our first to term. My OB has suggested blood testing to see if I have any conditions that may cause my body to reject the baby. The sucky thing is I have to wait until 6 weeks post miscarriage. I really want to try again now, but my husband is hesitant and doesn't want to watch me go through another loss. So, this last week three women I know have announced that they are pregnant and one is my co worker. Waiting is gonna be hard, but I know I cannot handle another miscarriage.
