The only advice I can give is to let your body heal. We had a m/c last December at 11 weeks and after 1 cycle we tried again and succeeded. Although getting pregnant was a success, we lost this baby to m/c again at 5-6 weeks. In hind sight I wish I could have gone back and waited longer. Especially after a D&C which can take longer for your body to heal. I would be patient and start taking Prenatal Vitamins and take care of your body. You dont need to try, just let it happen, your still so young.
I think you should enjoy being husband and wife for a while before you bring a 3rd person into the relationship. Enjoy it while you can! Good luck and SSBD!
I just started charting as well so I'm kind of in the same boat as you, hoping I can soon be proof that it does work, LoL! But I would like to think that surely it has to. It's better than just free-falling and hoping you hit it on the right day. I had an ectopic pregnancy at almost 7 weeks this February. We weren't trying but we weren't stopping it either. This is my third month (off and on) of charting. Two of those cycles I wasn't 'allowed' to try though so I was just trying to get a better sense of my cycle and normal bbt temps. So this was the first month I was allowed to try so hopefully I can be an example!!! It took three years of "not trying but not stopping it" to get pregnant the first time. So we'll see how charting compares. Good luck and ssbd!!!
