I need advice please

Yesterday when I went to the bathroom first thing in the morning I wiped and there were three spots of blood. The rest of the day there was no more blood but I smelled like I was  having a heavy flow. Today no smell and no blood at all. Af is due in about a week. I'm on 1000mg twice a day of Metformin and just upped my clomid last cycle to 100mg. Is it because of my medicine? Never experienced this before.
