Help !!

Hey everyone! So my fiancée and I have been trying to conceive for a few months now, and haven't had any luck. Well, recently I've been having a few changes in CM along with a few symptoms like light cramping, lower back aches, bloating,bsensitivity to smells and my temperature has been running extra high all the time (I'm going to school for nursing and we take vitals every day). My ovulation day was on January 25th and we BD'd that day along with my fertility days leading up to it. AF isn't expected until February 8th. I've thought I was pregnant before and it had been a BFN, so would it be possible that I am? Or is it too early to tell?
