ummmm????..

okay so i had sex unprotected so before anybody comes bashing me, i know what i should expect . but the last time was in december and in january i got my period, this month, i believe i went through a cycle change but i’m lowkey worried because i keep saying people say that they were pregnant and dealt with the same thing as me and had no other symptoms, i took a test and it was negative but i don’t know what to think because it’s saying that cycle changes are normal and i know that and there’s a lot of other factors (like i could’ve got a false negative) but what i’m trying to ask if, even though i have had my period twice and i haven’t did anything sexual since is there a chance that i could be pregnant?
