Infection after colposcopy?

I had a colposcopy a week today. Which they took a biopsy, I just wondered how you knew if you had got an infection? Sorry for tmi but they said you would have brown spotting. I’m more than spotting and also have blood (not like a period) also have slight cramping. I was just wondering if this is normal or could I have an infection? I was naughty and had a bath (no additives) so don’t know if this affected it. Thanks in advance.

Cramping I was told was normal. and to expect watery brown/red discharge. Any nasty smelling discharge or heavier blood is a sifun of infection I think. Oh, and my consultant said baths were fine!
