Help!! Period is late, but negative test.

​Just a little back story, just got out of a 4yr relationship where we were ttc for pretty much the whole time with no blessing, even after the break up we tried to coordinate some activities around my ovulation but no go. I have pcos which has made things more difficult. In April I was working out a lot and eating healthy, lost about 10 pounds. I'm dating a new guy who says he is very fertile ( lol ) and he kept telling me I'm pregnant, well before even being close to a missed period. My last period was April 10 to the 14th. We have had several sessions on the following dates: April 28th, 29th, May 2nd 4th, and 8th. All days with2.7%. According to Glow my period was due back on the 10th and still nothing. I tested three times with a First response test within the past 7-10 days and all of them negative. Today being the 14th still no Bloody Mary.  Am I loosing my mind. What's going on here? Please help
