Foul Smell?

I didnt confirm with my gyn but going from the faint lines I had on my pregnancy test days before bleeding I believe I was about 4-5 weeks along and lost it. Now 3rd day of very light bleeding I am noticing a strong odor. Any experiences/advice? Wondering if this is normal in general. I figured my body is expelling bacteria and such so its okay? Idk. No fever, but I am fatigued and have a major migraine all of a sudden.
