Bleeding during 2ww after iui

I an 12dpiui and today my boobs hurt and I just went to the bathroom and when I wiped I had a brown discharge. I'm suppose to go to the doctor on Monday. I do not have any early tests only regular ones. What should I do and is this normal or does it mean it didn't work?

Hi!
The bleeding could be implantation bleeding because it is happening at just the right time.
The breast discomfort is probably related to progesterone.
I would definitely recommend testing for pregnancy soon.  14 days post IUI is not too soon to do a first test.  
Good luck!

Hello: If you dont mind I would like to know the outcome.  I had an IUI dont on June 30 and 2ww will be tomorrow but for the past two weeks (with all the fertility meds) I have felt horrible.  Cramping, sore breast (inbelievably sore) neaseau, exhausted... all of the above.  However, yesterday when I wiped I saw the same brownish color.  Today - still not heavy if anything but not almost like AF is going to start.. Tomorrow is testing day --but I am very nervous that this is AF and not implatation bleeding.. Any suggestions?
