I wish I was pregnant again, and wish my husband would agree to try again when my son is closer to a year old. But he wants to wait until after my 21st birthday. I know I just recently miscarried but that would put us at trying in 6 months or so. Time to recover. Instead of 2 years. I want my babies close. He is just scared because of the miscarriage. And I did alot of very heavy lifting, and probably moving things I shouldn't have this past time. Feeling like if I didn't do the stuff I did I wouldn't have miscarried. I just wish he would agree but instead he keeps bringing it up to have them farther and farther apart.
