Feeling Discouraged

I’m 7dpo and all of my tests have been negative. I feel like I’d at least be getting faint lines by now if I was pregnant. I feel like I’m out this month. My poor husband probably thinks I’m up to something because I keep locking myself in the bathroom to take tests lol. Idk I feel a little “embarrassed” I guess because I don’t have anything good to tell him so I haven’t been telling him I’m taking tests. The only “symptom” I’m having is mild cramping and a little nausea here and there, but that isn’t much to go off of. Hope you guys are having a better TWW than me
