I’m 18/19 days late for Af , 55/56 days since first day of last period, I have taken two pregnancy test and both negative, I have barely been getting slight pms (or can be pms) these past three days but still nothing. I might have ovulated the 26th of December and that same day I had unprotected sex but he pulled out (I know it’s not a great method to use but it’s been working on me for the last 5 years 🤷🏻‍♀️lol ) do you think there’s a big chance I might be getting false negative?
