Help!!

So me and my boyfriend have had sex with condoms and he also pulls out before he cums. I am now 12 days late for my period but have had this white/clear slimy discharge this whole week. It had me thinking I was on my period :(. Am I late because stress, change of cycle or pregnancy? Ive had a light cramping. Ive been late 2 weeks before but usually have a normal period.
