We're making progress

We finally have an appointment with a new doctor. Our midwives don't prescribe any medications for fertility treatment so we had to change providers. Our new RE is, according to a friend who is a patient, really nice and knowledgeable. Our friend is straight so no word about how he is with same sex partners. Our appointment is April 16th. Hopefully we can start TTC again soon after that!
R is late again. Her cycles were like clockwork until about 4 months ago and then something changed. We're not sure what changed, but now her temps don't always behave and it's hard to tell from temps if she's even ovulating anymore. We were temping for months before we started TTC and every month she was ovulating on day 16 or 17 of a 28 day cycle. Our midwife was concerned about her LP being a bit short so she ordered testing and R's LP progesterone levels were really low. Also, R didn't ovulate at all that month.
Any suggestions about what we can do to try and get R's cycles back on track? We will be asking the RE the same question, but wanted to know if there was anything we could do in the meantime.
