Could I be pregnant? help!!

Okay so Ive been fertile since the 26 through the 31 of January. I had sex 27th all the way to 31st.. I ovulated on the 30th and 31st I believe.. definitely 31st.. now I'm having creamy thick CM.. I've had back pains and yesterday and the day before that I had digging pains on my right ovary. Today I've had hip pains.. NO SORE BOOBS. AF is due on feb 14.. could I be or no? I normally just have egg white discharge before period but sometimes creamy discharge before AF. Help?? Thank you so much!
