vaginapagina | Linea Nigra -- Does This Mean I'm Pregnant? (Reply)

Well, lately I've been having symptoms of pregnancy (I'm still waiting for my period which is due later this week). I made a post earlier but this is different.

My symptoms:
-Bloating (will not go down)
-Nausea that comes and goes w/o warning
-Tiredness, I just feel generally weak and more tired that usual.

(I was on Ortho Evra from June to September and stopped suddenly. I became sexually active on my last patch and contiuned to have sex unprotected)

MAIN QUESTION:

But my mom and my boyfriend noticed this line under my belly button, its called a "linea nigra" which gets dark much later in pregnancy. It looks like one, but its very, very faint -- you have to look at it for a second to see it. It runs from the bottom of my bellybutton down yonder. Could I be developing one now, or do they develop when you concieve and get darker over time?

I'm very confused on this.
