Very confused

So me and my husband have been trying for the last 3 months I felt like I was pregnant so I took a test about 6 days ago and it was negative :( was due for my period yesterday and I never got it 🤔 the last 3 nights I haven’t been sleeping at all but I don’t really feel cramps it comes and goes but it does not feel like I’m getting my period so I took a test today and it was negative again... has this happen to anyone where they were pregnant? Or is my cycle off also I’m usually always on time and regular! Help!!!’
