Positive yet? On cycle day 16 and still getting flashing smiley face on clearblue advanced(8days of flashing smiley face) but finally got this on a cheapy Amazon test.Also don't know if this has anything to do with ovulation but starting this morning I have been throwing up,fever,cold chills, upset stomach,no appetite,back hurting some and boobs .I'm usually never like this .
