I took a test before my period and it came  out negitive but I then took two more after I was pregnant and they came out positive.  I knew I was pregnant I had the feeling.  So just wait a bit and try again.

i had 4 pregnancy test dont 2 myself and 2 at docs all negative i was postive i was pregnant and so i got blood test i was, just goes to show that the test dont always work. go get blood test to be sure.

Have you tried the pregnancy tests that can be taken from 5 days before your periods are due? If you are pregnant it will certainly work.
Also, you could have a mild nipple infection or thrush of the nipple! I had similar to what you described about 6-7 months after my bub was born and never breastfed at all! I wasn't pregnant though.

If you are preggers, congrats!

A lot of pregnancy tests won't give a positive result until after your period was due again.  I knew after just 2 weeks, but that was unusual and the doctors were amazed it came out that fast.  Most of the time people are 6 or 7 weeks before a positive test comes up but usually they know it and the test is just to prove it.  I used to leak all the time! I still leaked more than 6 months after she weaned too, so it's a good indication unless you're breastfeeding now, it could be that.  Let us know anyway!
