Hi Tanners - wow, can imagine that it's painful & not pleasant... hopefully worth it though for a BFP at the end. All FX'd for you
I don't have any experience with IVF, but I have had a cone biopsy (3mm tumour removed, luckily caught very early on through smear test) when 31yr & a natural pregnancy two years later.
I was worried in regards to pregnancy etc but my specialist said cone biopsy was all healed & no reason couldn't have a normal pregnancy & delivery. As it was I ended up having an emergency casesar as DD was 2 weeks overdue & got stuck

But supposedly shouldn't be any issue with the cone biopsy site.
In my case the cone biopsy & lymph node removal was a non invasive surgery method to retain fertility as I was young & had not had a family yet. (Alternate treatment if you've completed family is apparently hysterectomy as that removes all cells/risk). So in that sense it was successful
I've now had the all clear check up wise for 4 yrs & only have to have regular smears & specialist said fine to TTC #2. But must admit it does prey at back of my mind whether the CB surgery has any part to play in our not falling pregnant with #2 yet, but probably that's just to do with age more than anything as just turned 37.
