Question

Okay so I was late for my period by like 3 days. When it came down, I only bled for 2 days. Mind you, my period is usually 4-5 days. So I stopped bleeding completely. Skipped a day till the next morning I woke up spotting. I went to go pee and as I wiped I had like a pinkish color. I spotted for maybe a few hours that day. I feel completely fine just slight headaches here and there and lower stomach and back aches. I did have unprotected sex a few weeks back. Should I wait to take a pg test or when would be a good time? Or could I be overthinking lol?
