I went to the health clinic

So today I went to the clinic for the morning after pill as I thought I could be pregnant due to unprotected sex, anyway, I could only be pregnant from Pre cum and now I’ve took the morning after pill, is there any chance I could be pregnant, this app says I start ovulation tomorrow and I had the unprotected sex 2 days after my period which makes it less likely for me to get pregnant anyway. Any ideas?
