drunk mistake?

so last night I got carried away with the vodka and the make up after an argument sex began. my period is already 3 weeks late and 4 pregnancy tests say negative. we didn't use a condom for the foreplay and somehow we started without the condom for a minute then I made him put one on and then,we,stopped because of drunk,emotional me. he didn't have any precum and didn't cum until 45 mins later with a hand job. do you think I'm,fine? if my period were on time it wouls happen in 4 days
