Random bleeding

Imani

So I ended my period about a week ago, but the following week I started lightly bleeding again. I've been on bc but recently stopped and only had sex maybe once not on it a day after i stopped taking it. Yesterday I started cramping up terribly and with a normal period i never ever cramp. The cramps got so bad i started puking and couldn't eat. I then started passing huge blood clots that made me think I was having a miscarriage, but I took 2 tests and both were negative. Tried seeing doctors at 2 places and both were booked. Was wondering if someone experienced something like this? I am still bleeding today but cramps are very minimal and no clots.
