3 weeks late

My AF was due on Jan 31, it has yet to start. I took a test on Tuesday and it was negative. I thought I saw a vvfl, but thought I was psyching myself out and blamed it on the fluorescent lights so I threw it away. Now here I am, 3 weeks late and feeling pressure in my lower abdomin (uterus zone lol). Kind of like bloating, not necessarily cramping. I haven't spotted and I've had a tiny tiny bit of clear mucus (kinda egg white). Anyways, now my breasts are starting to feel funny and I'm worried that I'm hyping myself up. Update: still no AF. Took 2 tests this am, one was a cheapy and this one. I think I see a vvfl. This is how the last one was. What do you all think? The cheap one was a BFN and no vfl..
