I just need help to figure out ealry pregnancy symptoms

Heaven

If anyone sees this can they please help me out. This past Saturday me and my bf were doing the deeds and he accidentally came in me and he freaked out and I said it will be okay. I told him I’m on birth control and that I can take plan B. I took 2 plan b as soon as it happened and idk if I’m pregnant or not. I don’t feel any different, the only thing that is happening is that I’m very bloated and I look pregnant. Is that an early symptom? I’m 16 and I really need the help. Can anyone give me advice with this
