OPK Help!

Bri • 23, married for 4 years, TTC for baby #1, miscarriage at 8 weeks in December 2014, rainbow baby due August 2016!
I got a positive opk today after just miscarrying earlier this month. My doctor said it was only for us to try again this cycle once my bleeding stops. So I just checked and i got a positive. We bd last night and I used a softcup and left it in place for 12 hours as instructed on the box. Now should we bd again tonight or keep with the every other day thing we have been doing? Help!
