Took a plan b and fear I might get pregnant anyway

I was intimate with my boyfriend and he came inside me. 4 hours after I checked if I was ovulating with the clear blue ovulation test and I was (I had just gotten of my period like a week before and didn’t think I would be ovulating.) I took a plan b the next day but threw up just a little bit about 1 hour later and didn’t think anything of it until i search on google and it said the pill doesn’t work if I threw up 3-5 hrs later. I took another one before the 72 hours but I took an ovulation test and it shows I’m not ovulating….will the plan b work since I’m not ovulating anymore?
