Help!

I'm so confused. So I had sex when I was ovulating. Two weeks later I was having so many pregnancy symptoms-extremely tired, heartburn, sore legs and back, headaches, strong sense of smell, cravings, dey mouth, enlarged breasts etc.  so I truly thought I was pregnant also because my period was late, but then I got my period. 5 days late. except it didn't feel like my normal period. there was no pain or discomfort, just bleeding. It was a little bit lighter and longer than my normal period. I thought for sure that meant I'm not pregnant. But now I'm starting to second guess because i see some women have had bleeding during early pregancy. Whether it be not enough  pregnancy hormone, a tear in the uterine lining etc. I still have some symptoms and my stomach is so bloated lately. I just feel so weird and different. I'm not sure if I could be pregnant or not , I will have to take a test. But in the meantime does anyone have any advice or opinions on this? Thanks!
