Anyone else experience this???

Little background: ive had 2 beautiful daughters and my fiance has a son. We have been ttc for 2 months. Im a pregnancy test addict at this point..... Tested 2 days ago and swore i saw a very faint tinge of a pink line but it wasnt enough for me to get my hopes up over... Recently CM has been very watery and milky in an unusually larger amount (it kinda feels likes im constantly wet). I only have 2 tests left and according to glow i shouldnt test yet but ive been nauseated severly sleepy with migraines and always hungry but things i usually eat make me sick..... I dont want to waste a test because i buy the expensive ones but these are the same symptoms i had when i found out i was pregnant with both my girls (by the time the doctor got the blood test back it said i was 13 days into pregnancy)... Does anyone else have experience with symptoms like this and should i risk using a test?
