Could I be pregnant from Pre Cum after taking Plan B?

8 days ago I had unprotected sex but no ejaculation. I felt great after so I didn't think anything of it until 24 hours later. I was googling and researching pre cum and sperm and pregnancy. So I texted the guy I slept with and he said get plan B. I took it about 25-26 hours after the unprotected sex. And I'm freaking out every day especially now because I downloaded a period app and it told me I had sex on my ovulation day plus I waited 26 hours to take the pill. The only symptoms I have gotten from the pill are sore/ tender breasts, cramping and pain by my left ovary. I still have sometime to wait on my period, and i keep googling pregnancy and plan b and it's been scaring me. If anyone has been in this same place, please share, and if anyone has anything to help me not freak out that would be nice too! Thank you.
