I'm scared😰

My periods are irregular and I had my period in May from the 20-27 . That last day I had sex . A week later I started feeling bloated and a little pulsing feeling in my stomach like a heartbeat . I shrugged it off , I had sex on June 3 and then I realized I haven't been pooing at all . Then I had sex June 7 and then after I started feeling the same symptoms so I started getting worried. I started taking 2000 mg Vitamin C daily and today I got cramps and it hurts after I pee and when I wiped I saw pinkish reddish light blood and little clot thingys. Could I be pregnant 😨
