Decisions??

I hope this is the right group to be posting in.... Please help me! Idk what to do, and my SO is not helping. He just says "whatever you think." But the problem is I'm unsure and need someone else's input. We've been ttc for a bit over a year now with no success. It took us 10 years to have our daughter. I'm teetering on getting more progesterone cream(to get my period going)or diet pills(I've been eating healthy, and exercising to no avail). Should I get the cream and keep trying or shift focus to weight loss? I'm becoming depressed, and don't have dependable gal pals to discuss this with. I just need some advice or encouragement either way. Feeling so alone, and discouraged.
