I think I’m pregnant?

Hello, I apologize if this is too much information, but I had unprotected sex a couple of weeks ago and recently haven’t been feeling quite right. I’m not sure if I might be overthinking things, but I wanted to ask for your opinions and see if anyone else has experienced similar symptoms. I’m also wondering if it might be too early for symptoms to appear, which is why I think I could just be overanalyzing.

It started with severe heartburn and stomach cramping , which has improved somewhat. I’ve also noticed a strong odor in my urine and some unusual discharge. One day, my heart rate suddenly increased, but after eating and drinking a Gatorade , it returned to normal. Lately, I’ve been feeling lightheaded, weak, and unusually fatigued—especially at work, where standing for long periods has become difficult.

In addition, I’ve experienced restless legs, increased tiredness, and digestive issues that feel quite abnormal. I’ve been very constipated, and today I noticed mucus in my stool for the first time. I also vomited today and have felt mildly nauseous over the past few days. Overall, most of my symptoms seem to be gradually worsening, aside from the heartburn, which has improved.

Thank you in advance for any insight you can provide. I’m hoping this is nothing serious, but I wanted to reach out for reassurance.
