Let down.. opinions?

I have cramping and mucousy white/clear sticky discharge. (It's like rotating between snotty and just clear) It's not really stretchy so I know it isn't ovulation.. plus I'm 4 days until af. And my cervix is only about two inches (little over half my middle finger) up. Ttc, so I took a test in case those were signs of pregnancy and it was negative. Guess I should have waited those 4 days! I'm torturing myself for sure. UNLESS I just tested too early because it was just an 88 cent test. Could I still be pregnant or should I give up for the month?
