Still late.

I'm 19 days late and honestly I know something is up with my body I've never been pregnant before but I feel "off" I tested when I was 16 days late and I was still getting negatives so I gave up and thought yea your not pregnant af will be here soon here I am 3 days later no period but I haven't tested I've tried soaking in the tub and trying to bring my period but I do not feel like I'm gonna get a period anytime soon.
