lactation

So I have an odd question for everyone. My husband and I have been trying to conceive since 11/16 after being on the pill for 4 years. Anyways lastnight before I got in the shower I had been having some breast pains. But that's normal for me when I'm close to my period. Anyways when I looked in mirror I notice I had a clear, white discharge coming from my nipples. Keep in mind my nipple look normal to me, not red or etc. the discharge looks just like breast milk. I have been nausea for the past few days. Again that's my normal but my reflux has been acting up more than normal. I have PCOS so I never know when my period is coming. My last period was 5/1/17. So I took a test today and it was negative. I am trying to find out if anyone else has had this before????
