So I am 18 days late with confirmed ovulation. I was wondering how long I wait to call a doctor? I have taken multiple pregnancy tests with several different brands and basically they have a been negative except a couple of suspicious evap lines. Has this happened to anyone else? I’m not stressed, there’s been basically no new stress in my life, no body changes, nothing that would stop a period from coming. My husband and I have been trying for 3 years. No symptoms of pms or pregnancy. 🤔
