Ttc question...help!

So... in short, I had a positive ovulation test on Monday just past.... with very minimal ewcm, cervix was high and open.... today I have a negative ovulation test, but tons of ewcm, cervix is high again (it was low/med on Wednesday-Friday) and I can’t feel an opening.... should we bd again? ... I’m thinking yes, just incase! Has anyone had this before?! I’m not super familiar with the effectiveness of opks! Help!
