If you have a yellow discharge then its likely that you have an infection, but I don't think that would affect your cycle. You should speak to a doctor about this discharge you're having.

Are you worried about this? Stress can delay your period.

no i am not worried or stressed, i am not taking any birth control or do we use any. the discharge like i said is clear but sometimes when on white toilet paper has a slight yellow tinge to it.

Yes, you could still be pregnant even though you had a negative pregnancy test and the yellow discharge sounds like an infection.

hello, i am in the same boat. i dont want to give your hopes up or excite you when you may not be but with my first pregnancy it didnt show up till almost 2 weeks late. my sister in law waited 12 weeks and finally got a blood test and it was possitive and guess what she has twins! The doctor told her that being pregnant with twins blocks the HCG and a pee test does not show up. He also said dehydration will cause a false negative. Hope this helps. I am suppose to start yesturday or today and nothing yet. Hopeing for twins since it runs alot in the family!
