I am two days late of my period and I have been feeling some pregnancy signs, though I'm not for sure they are signs of my period coming on or not...I have been cramping a little bit and having headaches now and then and when I feel for my period there is this white milky discharge sometimes. I stuck my finger in my vagina and I believe I felt my cervix. It was pretty low. Could all of this be signs that I'm pregnant? And how soon should I take a pregnancy test
