Chance I’m pregnant

Right girls, today I realised that there is a strong chance I could be pregnant but the issue is that I’ve been drinking over the last week. It has only been a glass or two every other day. I have no way of getting a pregnancy test and am wondering what I should do??

Edit: The reason I think I’m pregnant is that I’ve had bloating over the last week or so, I’ve been waking up nauseated and that has been lasting most of the day with the smell of some foods making me feel even worse along with increased urination and fatigue. Also, my period was due three days ago but nothing so far.
