no af

Amelia
I am cd37 and still no af and no bfp. Last month I went 43cd before af showed up. How am I supposed to keep track of everything if af keeps being crazy. I bought opks and I have gotten positives and we bd 5 out of the 7 days that week. This will be ttc month #6 if I don't get a bfp. I could really use some advice or good vibes with some baby dust. Thanks.
