cervical screening and abnormal result

Hi, so I don't really know what to say. I'm 20 and 6 weeks ago I got my first smear test and the results came back saying mild changes. I was given barely Any information on my test results and so I'm really terrified and unsure of what it means. I was having strange and random bleeding before my periods which I had today. Also had bleeding after sex twice. I know it's probably nothing but if anyone knows any more it'd be really good cuz I'm going out of my head and it's driving me crazy. 

Have they asked you to go for a colposcopy? Mild changes are very low - they often clear up by themselves.
