HHEELLPPP!!! A little long

So I my partner and I had unprotected sex during my ovulation week, NOT the day of, two days in a row and then again on the 13th. Ovulation predicated to be the 14th, sex occurred the 10th and 11th and the 13th using the pull out method only on the 13th.The first time after we had unprotected sex and he finished inside me I went out and bought a plan b pill. Now I know plan b won’t work if you have already ovulated. I’ve been using ovulation strips since the 19th. The test line on the 21st was my darkest but not a positive and now the line is getting lighter. The question is could I still have ovulated on time even though I took the plan b? Panicking because I’m nauseous, tired AF and boobs sore. My boobs don’t get sore leading up to my period. Just a fyi. Help!!!!
