You are around 21 weeks? Blood clot is definitely not normal. Please get a check up for the peace of mind
If you haven’t full term... it’s not normal. Please go to the hospital straight, don’t wait.
I agree u should go A & E since u said u have low placenta .. and u had a fall earlier
I will be worried and I won’t take chances. Please go see a doctor asap.
Really need to go A&E now. I hope all is well.
I feel you should call your gynae and check.
Better to go for gynae
better to see a Dr
