Has anyone had heavy bleeding mid cycle on clomid?

I had horrible pain in my lower right side with moderate bleeding for 1.5 days and spotting for 1.5 days. My doctor was no t concerned. One day I was in so much pain I stayed in bed. I thought it was my period. I have never take. Clomid before. The following week I had a little brown blood when I wiped a couple times. I have no clue if I ovulated because I did not know I had to take my temps. I do not want to take a pregnancy test. I am so sick of the bfn!!!!
