I’m going crazy!

Lauren

So I was supposed to start on the 31st, and I only had a light spot when I wiped late that night. The next night same thing super light spot. I took a couple tests one Thursday night and one last night and they looked like they could’ve been faint. One was an off brand blue dye and one was first response. Took a clear blue today same thing, and then took a digital it was negative. I’ve never been late and spotted the day I was supposed to start. I’ve been cramping since last week, today they have stopped, and I’ve been super nauseated. My mom is convinced I’m pregnant and it’s just too early. Has anyone ever had this happen what was your result? I have 3 boys and with my first I was late and got a positive with my second I felt pregnant tested it was negative but hadn’t missed my period yet, tested 5 days later and got a faint positive, and with my 3rd I had a feeling I was pregnant and had some thick creamy discharge so I tested and it was negative retested 5 days later and got a super super faint positive, I don’t know if I was late with him because I hadn’t had a period in over a month but when I found out I was super early. My second I was super early too I didn’t even have a baby or a sac on my first ultrasound with either of them.
