Ovulation help

Hello! I’m new to the group and new to ovulation tracking. Last month was my first month tracking. I had a positive on CD 11,12 &13. I’m not sure if a surge is supposed to last that long but the lines were dark on all 3 days. However I did not get pregnant. This morning I started tracking again. I am on CD 10 and it looks like a positive to me. I took a clear blue digital and got a non flashing smiley face. We bd last night. Well- this morning. It was around 1230 and then around 230. Yesterday my strip was negative. My question is should we bd tonight again or should we wait until tomorrow and take a break. Thanks for your help!
