EWCM - Ovulating

I really thought I ovulated on the 5/6th since I had ewcm and it was stretchy. Today, I was randomly checking my cervix and I have ewcm again. The only difference is that my cervix was open on the 6th and it feels closed today. I didn't use opk's or check my temp. I have been cramping ever since. It feels like period cramps with mild lower back pain on my left side. I never "dried up" after ovulating. I plan to take a pregnancy test on the 19th if my cycle doesn't show up sooner.
