White Milky Discharge?

I started BC on Feb 20th & it was the first day of my period. I stopped BC 2 weeks into my first pack because of the really bad side effects, I had unprotected sex after stopping it, then had breakthrough bleeding on march 7th & with some EWCM. I bled for 4 days, it was spotting b/c everytime i wiped, it was so light, like barely any blood. I had unprotected sex on March 9th 10th 11th and 14th. If I was still on the BC, I would be on 1st day of my next pack. I didnt get any bleeding during the last week like I was told I would. Before I got on BC, my periods were regular and 26 days on average, so if I was to get on my period, I'm 2 days late. I've been cramping for the past 3 days, and usually when I cramp, I'll get my period the day after pms cramps, but it's been 3 days. I've also gotten some milky discharge that has increased since. Ik BC throws your cycle off, so Idk what to do.. should I test tomorrow morning or wait?
