I am 10w3d and since last night when I wipe there is brown blood. The office was closed today so I have to wait till Monday for a scan. The on call dr could care less that I'm having some bleeding. I know everything could still be fine but I'm so stressed especially because it's been a day and hasn't stopped. I am not having any cramps. I just feel super bloated. The dr said the er would refuse to see me because I'm not having major bleeding. So how long did spotting last if you had it? Other than this I have had zero issues so far.
