can someone take a look please?

So I only chatted after I ovulated. I ovulated on Jan 13 (my chart keeps updating BBC I have been pushing back my period). I have been nauseous and having all the signs of being pregnant. Got a very faint line on Friday January 27, and Saturday had weird uterus pain not like a period, and some spotting. Saturday night I had excruciating pain and lots of dark red bleeding and clots for 5 hours then it stopped . Slight spotting yesterday and Sunday with the same unusual pain on and off. My temps dropped Day before and of my horrible episode, but are rising again. What does this mean??
I went to the doctor yesterday and had an ultra sound and blood work. Waiting on results. Thanks in advance for your opinions.
