CM? (TMI but no pic)

Okay this is hard to explain.
​But I am currently 9DPO, my AF is due on 28th September. Me and my fiancé BD'd on my peak day, and have done every other day before and after that. 
​The only symptoms I have noticed are sharp stabbing pains on my right hand side of my uterus a few times a day, and I just checked my CM and the only way I can describe it is it feels kind o lotion like? Like egg white but not as stretchy! But it slippery. Not sure what it means! Anyone know? :(
