Bleeding all of a sudden - 6 wks post-op

I had a TAH 6 weeks ago to the day - recovery has been slow and basically uneventful and all of a sudden this evening I'm bleeding (the amount is comparable to when my periods would just start) Why now? Has anyone had this happen and what was the cause? I've been very careful about lifting etc....
Thanks for any advice/input....

I would not hesitate to call your dr or if it gets to be heavy to go to the ER. on 1/26 I went to the bathroom and had bright red blood like the start of a period and freaked as I had not had anything like that for the entire time since the surgery. I called the office and was told that it was normal and that if I did not bleed thru a pad in 1/2 hour that it would be ok but to call or go to the ER if they were closed. Please do not take any chances with your health. Keep us posted.
