Sorry to hear what you are going through. Whilst I didn't have a visible growth on my cervix I can relate to you feeling annoyed about the possibility something more could have been done previously or something was missed in the past. I had my last pap smear 14 months before with similar complications as you and I was told everything was fine. Then I was straight to CIN3. So obviously something was missed.
I am a little unsure if you meant you had already had the colposcopy? If you have, during the colposcopy they apply a Acetic acid solution and iodine solution to the cervix to make the abnormalities visible and after the biopsies are taken Monsel's solution is applied to control the bleeding. The discharge is normal and for me I guess smelt a little like vinegar. However, if you are feeling it is not along these lines then contact your doctor to ensure you don’t have an infection. I don’t believe an infection could develop so rapidly though.
As for the emotional rollercoaster you are completely normal. I cried so hard when I was first told about all of the ‘possibilities’ that my nose bleed, I’ve never had a blood nose in my life. It is something that only someone that is going through can understand fully. Bless your husband for trying to calm you; I guess he would be scared also and perhaps with a little less understanding of the female anatomy. I ended up sitting down with my husband and watching a few (cartoon) explanations of what was going on with each procedure.
Just please know that the initial shock is the worst and our human nature is to become adapted to the situation we are in so it becomes a lot easier and less confusing when you go through the stages. I am just so happy that finally someone picked up what seems that have been causing your bleeding and you can get set on the road to treatment. The ladies on here have been a life saver for so many, me included, so when ever you need some advice or a proverbial hug you know you will get it here.
