Oh you poor thing
Yes, I have bled that long (8 months, in fact) as a result of a polyp which was missed during a biopsy which I had without any pain relief. I couldn't bear the thought of going through that again and probably put it off too long. In the end it just got me down, dreading going to the loo, constantly having to wear a liner and the background worry of what if it turns into something more than a polyp. fwiw I was assaulted when I was 21 and find any kind of internal examination a real trial, no matter how kind and patient the practitioner may be. In the end I opted to go for a full GA and am so glad I did. That was two weeks ago, and apart from the first two days when I needed a pad, I've had the scantest of blood since then which I was told to expect. 99% of the time there is nothing and I'm sure it will get to 100% soon. It's been such a relief. You wake up and it's all over and you don't have to worry about it.
You can have a GA for polyp removal and I would honestly recommend it. The consultant I saw said hysteroscopy and polypectomy is one of the easiest procedures she does as an obgyn, from me going under to coming round was less than 45 minutes and I was having a cup of tea 5 minutes after waking up. The recovery from this has been quicker than the biopsy back in April when I was awake, even though, as well as a polypectomy this time, I had another biopsy AND a coil fitted AND a hysteroscopy. I would say the reason for that is because in April I was scared, in pain, and tense, none of which applied this time as I was out like a light.
I really would recommend asking for a GA and getting that polyp removed.
