Can bleeding from op mean you can't be pregnant?

I had a laparoscopy last Monday I'm still bleeding getting quite worried as I've bled all week now assuming af has turned up a week early because af is really bright red, don't know what to think done test digital one yday said not pregnant but I was only 11DPO then I will try on the 15 is af dosnt show then but assuming I'll get another bfn. Could I still be pregnant if I am bleeding from my operation
