I am 8 weeks pregnant. And I just fell down a few steps on the stairs 30mins ago. I felt a sharp pain in my tummy and now, I just saw blood on my panties. Am I losing my baby?!! I'm really scared!!

Please go and check with your gynae as soon as possible! The first trismeter is where your body is really fragile, and the fact that you said that you've seen spotting right after your fall is quite worrisome. Please go to the doctor and have yourself check as soon as possible as they would be in a better position to access you.
