White discharge instead of Period?

This month, I did not get my period but instead I got white discharge. I am currently on the pill, Junel Fe 1/20, and have been for the past year and usually use condoms on top of the pill. However, the last time I had sex with my bf we used a condom but it broke so we took it off, continued without one and he pulled out before he came. But since I haven’t gotten my period this month (I start my new pack today) I am nervous I could be pregnant? I have had some cramping and back pain/PMSing but nothing like I normally get. I also have felt like my period has come but nothing is there.

I haven’t missed a pill, but sometimes I’m like three hours late taking it but that’s every now and then. So I’m not sure if I should take a test or not?
