19 DAYS LATE, NEG' HPT. HELP!!!

I'm 19 days late!! Last period was on Sep 25th. I've never missed an entire month before, I've only been 1 or 2 days late at the most. I'm 24, have never been pregnant before, not using any form of contraception, hubby uses the "pullout" method. Tested twice on the day of missed period (Oct 26) with Dollar Tree tests, both were neg. Tested again on Nov 9th (13 days late), still neg! I have a bunch of preg symptoms, I'm nauseous, sensitive to smell, back hurts, tired alllll the time, nipples started hurting yaaturday (18 days late). My husband & I aren't ttc but if we're are pregnant we'd be overjoyed! Just wondering if anyone has experieced this an what's has the outcome been?

i did i went for almost 5 months without a period and  it came. My doctor said its normal for periods to leave like that as long as it doesn't go over 6 months. Thats when I was told I should be worried. All pregnancy test and ultrasounds at that point were negative
