I had a LLETZ procedure 9 days ago and despite some initial bleeding/watery discharge for the first couple of days, I've mainly had a watery yellow discharge since (with dark brown/black grains which I also had after the initial biopsy) and I understand is normal and hasn't caused any concern or pain. Yesterday afternoon I noticed that the discharge was a little pinker when wiping but for the most part it was still yellow on the pad. Last night I went to the toilet and when wiping I found an orange mucus lump of goo (sorry for that detail!) and much darker charcoal-like lumps with this which was different to the dark brown/black grains I've had. I haven't had anything like this since but I did wake up with very mild cramps for about an hour in the night. This morning I went about my day as normal and this afternoon my discharge on the pad was still yellow my but when I wiped at the toilet it was pinker than yesterday. I've just changed before bed and this time my pad was no longer yellow but full of the pale pink discharge instead and when I wiped it was pinker than previously. Is this normal and part of the healing process? 
 

I should add that it doesn't smell at all really and I haven't had any cramps today. I also wasn't sure if this could also potentially be breakthrough bleeding although I haven't had a period in 9 years or any breakthrough bleeding in years either. I did take a little time to heal from the initial biopsy too as I had the after effects of that for around 3 weeks so not sure if it's also just my body being slow at healing! I'm not sure if I should also be changing my pad more frequently too or not as I'm currently changing every 4-5 hours which seems to work for the fluid build up in the pad - it's been a long time since I've had to deal with pads like this! 
 

I don't really want to call my GP on Monday as they aren't particularly helpful (I called them for my results of the initial biopsy at the first colposcopy and was told it was at the GP's discretion as to whether they'd call me back and inform me of the results - this was over a month ago and still haven't had a call from them to inform me. Luckily I called the clinic directly and a nurse called me back to inform me of the results and the follow up procedure as I didn't receive a results letter!). So any advice would be amazing!
