Help please

According to the glow app, I am 2 days before my period starts. I have taken a couple tests here and there during the tww. I took another today, and another negative. I have had barely any symptoms and my bbt has been all over the place. Should I just wait 2 more days and test again. I think I am pretty much out this cycle.

My hubby and I just started trying Valentine's Day for the first time. I'm 28, he's 29. Should we go get a blood panel done or something? Make sure everything is working?
