I also had very low temps like that, and I got pregnant with no problem-- about four months. If you are charting and don't conceive within a few months, though, especially given the fact that you have some known health concerns, it might be worth following up. Low progesterone can also cause low temps. FWIW, you might think about acupuncture. It's a great way to help normalize hormones and get your body ready to conceive. Good luck!
