18 days late with BFNs. Help!

Aubrey

Pretty much like the title says. I'm 18 days late and I've taken probably near 10 PTs, all negatives... 3 or 4 different brands. I've only ever been 8 days late because of stress before. My husband and I are on month 8 of TTC and I have no idea why I'm so late. Anyone had this problem before? Were you actually pregnant or was it something wrong? I want to hear some women who have gone through this because its killing me! Thank you💙
