is this possible? please help.

i’ve been feeling super nauseous and sick these past two weeks. me and my bf have been having sex. i’m on the pill but i usually take it between 10-12 so not perfectly. i skipped a pill this month too. i took 2 in a day to make up. we’ve used condoms as well and i’m pretty sure they didn’t break but i didn’t fill them up with water to check. could i be pregnant? or do you think there is a chance??
