Early period after Colposcopy?

I just got my period this morning and am not due until Wednesday next week. I’m on BC and this has never happened before. I had a colposcopy and 2 biopsies taken 3 weeks ago (still haven’t got my results!) but I am wondering if this has somehow caused an early period? Perhaps due to increased stress? I also feel rather nauseous which also never happens when I get my period. My skin has been breaking out like crazy so I am thinking (hoping) it is just because of the stress I am experiencing and not something worse?

Hiya... funnily enough I'm also due on next Wednesday after having a colposcopy and biopsy taken 3 weeks ago tomorrow. I actually came on on the morning of my appt. 

Was also wondering if my periods were gonna be messed up.  I didn't notice a bit of spotting when I wiped earlier however... because of a watery discharge here and there and then a bit of bleeding which didn't know if  was down to period or biopsy treatment...  so at the moment I really don't know what's what xx
