sosos

i usually taken my pills at the exact same time but last cycle i skipped a lot of sugar pills and then i took a pill from the first week 2-3 hours late and had unprotected sex two days later.. although he pulled out. now it's about a week after and i'm feeling nauseous after eating, tired ALL the time, and i find myself peeing more than usual. i know that my anxiety could be causing me to not feel good but i need opinions??? how likely would it be that i was preggo?
