No period

My last period was January 9th. My period was supposed to come February 11ty according to glow. I'm pretty regular, usually my periods are off by about a week. I'm sexually active but almost never use a condom. He pulls out before ejaculating and does so after sex with my help. No pregnancy symptoms  I've just been sick (cold) regularly for the past month and there's white discharge from down there. I'm a bit worried.
