Confused

So today at 1 am my husband and I did the baby dancing and the. At 11:00 am I started cramping and went to the bathroom and when I wiped there was blood and when I got up of the toilet there was a small blood clot in it. And now I am cramping but my opk is reading high

Plus the other day 2 days after sex I spotted

We’re not having rough sex so no reason to be bleeding

Has anyone had this happen if so what caused it ?

Also with this is there still a chance to get pregnant?
