AF decided to show her ugly face today! :(

I had a miscarriage last month and heard your really fertile after a miscarriage so I was hoping maybe I'd concieve again right away! Not the case! Been getting a BFN past few days so I guess it's back to BD after my period ends! I did get a positive opk 2 weeks after I miscarried but it's not a guarantee that I actually ovulated so past few days I started tracking my bbt in hopes that will give me a clue when I actually have ovulated! Sad to see AF start but hoping & praying next month will be a BFP for me!!! It's so frustrating!
