I think you have time, but an early test around the time your period will come because it won’t be enough normally if it just happened. Don’t be embarrassed about foreplay, It’s normal!
I get those symptoms when I ovulate. 🤷♀️ like others have said, track your symptoms and wait it out. Wait until you period is due to start considering pregnancy.
Taking a test won't hurt any, especially if it will give you a little piece of mind for now. If negative wait it out and if period is late take another.
I would make note of your symptoms in your cycle tracking app and wait it out. Then buy a test a couple days before your period is due if you’re really worried or wait to see if your period is late or not. You could take a test now but it likely won’t be accurate this early in your cycle anyway. There are lots of support groups and resources for unplanned pregnancies if you plan to keep or not, you just have to look for them. Hope this helps. Good luck
