I'm I pregnant?

I been having cramps since yesterday and I went to check in the bathroom but I didn't see anything on my underwear but when I wiped I saw blood this morning but the blood is not on my underwear it's only when I wipe I'm soo scared that I might be pregnant because 5 days ago me and my boyfriend had sex without protection and he told me that he cumed in me but I didn't take him very seriously cuz he always says that and nothing ever happened
