So I will be 4 weeks pregnant tomorrow which will be 17dpo. I got my bfp at 14dpo. I have been having on and off light cramping randomly throughout the last 2 days and around lunch time today when I wiped after using the restroom I had light brown blood. I know that the spotting itself isn't cause for concern but because of the light cramping I'm a little worried. AF would have been due today. I have attached a photo of the discharge. Can anyone ease my mind? I took a frer at around 4pm today and it was darker than the one I took this morning.
