I don't know the next step here...

So I have not had a period since August. I have taken 3 tests and all were negative. I have had no signs or symptoms of anything unfortunately. I thought I saw more veins in my breasts but I could just be seeing things because of how bad I wish I was pregnant. I had some spotting a few times last month and some cramping here and there but it was always very light, like when you first start your period, but then it'd just stop a few hours later. Everyone I talk to says I'm more then likely not pregnant (supportive huh?) So I don't know what else to do. Should I take another test if I don't get it this month either or what? I'm scared all this will be nothing like always and I can't take much more disappointment but I don't know what else to do.
