Unsuccessful sweep and clots

Vic

So I’ve just had my 4th sweep with my midwife which while the last three have been unsuccessful because my cervix was clamped shut, she did manage to get a finger in today however she said the top is still closed but the bottom is opening. Not 10 minutes after I’ve arrived home from the doctors which is 5 minutes away I feel a small gush and there is lots of blood which she said would happen but also a clot, it looks different to my plug which started to come away a couple of weeks ago. Anyone else had this?
