Hi!

 So my last period was the 22nd of April till the 26th. Then May 1st till May 4th I had light spotting with some cramping. Then May 25th till 27th I had very light spotting with a clammy feelings down there :/ ... My actual period was due May 28th but nothing came. Now I've been having clammy feelings down there again with a lot of white milky discharge. The symptoms I've had are very slight nausea after smoking, or in the morning here and there. I always feel hungry but when I take a bite of anything I loose my appetite immediately. I'm super tired all the time, and do crave Carbs ALOT!! I have taken 4 pregnancy test in the last month and all negative, if nothing by the end of this week I will take another! Help please, any advise or anything!!
