Fertile window

Hi everyone,

My boyfriend and I have been trying to conceive for 5 months and so far nothing. I’ve been on birth control for 5 years and came off in January. My periods are regular now. We bought preseed and tried it one night so far. I have been tracking my CM and noticed only in February I got the Egg white CM but since then haven’t necessarily noticed it again. It’s my fertile window right now and I don’t notice any discharge in my underwear at all is it possible I’m missing it when I wipe or what? I had discharge once like 3 days ago but it was sticky and thick. Any advice or thoughts please guys I need to know and I’m at a loss for what to think. Can I still be in my fertile window without seeing discharge?
