how long will this go on?

I'm hoping someone might have some insight for me. I had a TVH 4 weeks ago and I know the nurse said that I might see some bits of sutures (as they dissolve) when I wipe, starting around the 2 to 3 week mark. I had the odd bit around that time but I've noticed that during the last few days that I'm getting a little bit every day, usually preceeded by a sharp twinge and then followed by lots of renewed reddish spotting. Is this still normal at this stage? If it is, how much longer can I expect this to go on. It's just getting really old really fast.
Thanks

I think some women pass stitches until about 8 weeks. I saw 2 around 3 weeks and that was it for me. Some don't ever see any.

I think you are ok. But if your uncomfortable about it call you doctor.
