When should I test ?

I got my Birth Control removed in June ( nexplonon ) and my husband and I been ttc since while he was home (military deployment). From June to November my period was pretty regular until December when I got that long period of painful , heavy bleeding and lots of clots that didn’t stop till almost end of January . Since then we’ve been trying to be consistent with ttc every other day . I haven’t had a period this month and for a couple days now I’ve been feeling nauseous, headaches , sleeping a lot , light cramping , bloating . I had heavy white/pale yellow cm 3 days ago so I took a cheap test but came back negative . I don’t wanna get my hopes up . Should I wait longer or is it nothing ?? Does it mean AF is coming ? What are opinions y’all have for me ?
