Welcome to MDC!! I'm sorry that no one has responded to your post yet! I'm also sorry you've been having a hard time TTC. If you search this forum for "natural progesterone cream" and for "NPC" you'll find quite a few threads discussing dosage and how well it works. There are also several threads on clomid, including a recent support thread for those using it. Check it out! In addition, there is an entire Infertility forum for those that have been struggling to conceive for a while. You will likely find additional support and advice there. I hope that helps.
Do you chart your basal body temperature and cervical fluid? Often this is the first step for truly identifying problems with your cycle and determining possible solutions. It also helps you to time DTD well to increase your chances of conception. If you're interested in charting, just post for more information! Good luck!
