Missed one day?!

I’m on my second month of the pill and usually take it at the same time everyday. However, I took the first pill of the second week of this month over 4 hours late. My boyfriend and I then had protected sex the next morning but I didn’t check the condom. This is the week of my inactive pills and my period will hopefully be here tomorrow. Ive been waking up feel sick at the top of my stomach and burping a lot, seems like acid reflux. Boobs look bigger and a more sensitive. I took a test on the first day of the sugar pills and it was negative but I was drinking a lot of water. I plan to test tomorrow but does this sound like a chance of pregnancy??
