Bleeding

So a few days ago I was 8 weeks 3days, and I went to the bathroom and noticed a little bit of blood. But I didn’t worry too much cause there was hardly any there when I wiped and it had a brownish color to it too and I read that “old blood” is very common. Anyways, now I am 8 weeks 6 days and I have a yeast infection and with permission from my doctor I am using monistat at night time to get rid of it, and this morning I went to the bathroom and wiped and the extra medication that came out had a pink tint to it... but I wipe a second time and there isn’t anything.

Should I be worried at all? Or does this sound kinda normal? Also I don’t have any cramping at all.
