I'm about 16 dpo and took a pregnancy test about 3 days ago,it was negative. I've had no sign of my period but I've had belly cramping,nausea and dizziness. Also some other weird signs but I'm just wondering if this happened to anyone else? Normally if my period is late,5 days is the latest. I've been trying for almost 3 years now and still no luck. Should I wait and take another test next week? I just really don't want to get my hopes up.
