Awaiting colonoscopy results after abnormal smear test

Hi! 

I just need to talk to people who have experienced the same thing while I am awaiting my results  

I had a high risk HPV and CIN1 diagnosis on my smear test. I am 25 with two little children and I have recently had my colposcopy. 
 

I had biopsy's taken and the majority of the opening of my cervix showed abnormal cell growths. 
I had this two weeks ago and I am still waiting the results and I am worrying. 
 

I have a few questions if anyone can answer. 
1) if I need these removed, will it affect fertility? I am unsure if I want any other children later in life. 

2) would giving birth 5 months ago have anything to do with these changes? 
3) I had and still have, cervical erosions while I was pregnant - does this play a part in the changes to my cervix? 
4) is CIN1 precancerous cells? 
5) I also have adenomyosis and endometriosis, does this have anything to do with the changes?
 

thank you, I have anxiety and I overthink. I always tell other not to worry until you need too but when the big C is involved, even if it's not that, just being tested for it is very hard to digest and relax.
