Yes, it was both bright red and dark red and then much darker red (sorry guys!). It was not so much that the volume increased in the beginning, but that it kept coming out for four days longer than normal.
I hope it was house cleaning. I have never had a problem getting pregnant. My problem has been staying pregnant passed the six week mark. That is why I think it is hormone related. Especially as I recently found out I am low in progesterone.
