Colposcopy without biopsy and bleeding

Hi, sorry for the question but I need a help..Two months ago,I felt pain,itching,burning in my vagina. I am 32and reagulery do my pap. So I went to my gyno. She did pap and Hpv test. Both came back normal. But I feel pain..maby in vagina or around old episiotomy scar...So two days ago,I had colposcopy. Gyno said everything is fine,she dont see anything wrong. My diagnosis cervical leukoklapia. But one day after colposcopy I had sex and saw light blood discharge after it and I feel pain. I am in panic. Can be some blood after colposcopy? it was without biopsy.  Can my doctor missed something wrong??Maby I have to go for another gyno?
