Been trying for 3 months .. Still no BFP

I had IUD for 3 yrs. Had it removed about 4 months ago. We have been trying for 3 months now and still no BFP. AF last month came in 24 days and this month, if I go by what Glow is telling me, I'm late by 2 days. Took a test and BFN ! I need positive help ...
