Welcome! So sorry to hear about your loss.
This board is great to help with learning what to do for TTCAL, and these ladies are an awesome support system for those days you just aren't feelin well about the whole thing.
I'd have to go with the advice from above as well. I'm trying to fix my diet, exercise, remember the prenatals, and just get my body ready as well. It's not as easy as one would think, but will be sooo worth it when you see that BFP.
My piece of advice...don't be TOO hard on yourself, and don't give up. A woman on another board I was on once said, "Trying to conceive is not a race, it is a marathon." So try to remember that even if it doesn't happen right away, it will, and keep up hope. Good luck on your TTC journey!!
