Tara, I have noticed quite a bit of EWCM when BF both my kids. The first time I didn't get AF for 8 mth this time round I thought I had AF back at 7wks, had another breakthrough at 11wks but so far at 17-18wks nothing more so I'm assuming it wasn't AF. I too had O pains around 6wks and I think it's just your ovaries shifting back into position.
