Af is here.... now what??

For some reason my husband and I thought this month was it... and then af came right on schedule today 😩 I’m feeling the usual... sad, frustrated, discouraged. I also feel the need to step up my game a little, my cycle is like clockwork, I use opk’s and we bd almost every day during my fertile week and on ovulation day. I take prenatals and watch my diet, but other than that what else can I do?? Any advice would be wonderful! I’ve heard a lot about Pre-Seed, I think we might try that.
