AF came :( advice for next month!!

I would try using opk to get a better sense of when you ovulate. Good luck!!! 

Preseed and diaphragm/softcup, charting with bbt, CM, & CP- try reading Taking Charge of Your Fertility (I also use Kindara for charting- much easier to read charts IMO). It can take a healthy couple 6-12 months with no fertility problems. Going on month #2 myself and just had a huge reality check that I'm starting to accept we may be working on this for awhile. Good luck!
