37 days late...bfn

Uggh..I've missed 2 periods now and still have negative test. I've had 2 kids and I've always gotten late positives, but only by 2 weeks after missed period. Somedays I feel like I'm pregnant but I sometimes think it may just be mental symptoms.....we've been ttc so I really want to be pregnant. My dr said to just wait it out and that AF will show up sometime. Has anyone had this happen to them? 💕
