Urine Colour Change

Hello I'm 19 years old 👋🏼 My name is Alakia or you can call me Heidi 😊 I recently noticed a weird colour in urine and it smells strong for some reason. I had sex on the 9th of October and ever since I've had cum inside me. My urine smells stronger and the colour is a yellow colour kind of tinted. So I'm currently curious 🤔 to know what it means. I hope I'm not pregnant I'm only 19 so If a change like this is a bit drastic with a strong odor or ombre colour effect. What does it mean? I googled yellow urine means early pregnancy but I take the hormonal contraceptive pill 💊 at night 🤷🏽‍♀️ I don't know what to do. Invest in a fertility test to check my fertility or figure out to get a pregnancy test.
