Can I show pregnancy symptoms after a day?

I had sex yesterday and the condom broke and we were both really wet. I started getting cramps last night, about 6 hours later. I took maybe 5 of my Zovia 1/35 before I went to bed and this morning I woke up feeling nauseous and overall really sick. I ended up puking and feeling better for a while. Idk if I'll puke again but I'm really nervous. And we can't find anyone to get a morning after pill for me.
