My friends scaring me 😕🤰🏽

Ok so, I haven’t been feeling well lately. My back was literally hurting so bad today that I cried, I’m super gassy, been cramping , my breast feel heavier than usual, I’m bloated and my appetite is so off and on. I was craving shrimp rolls and spit it out after the second bite. Mind you, I’m on the pill. That’s the only form of birth control me & my boyfriend use and sometimes he blow the city up. I’ve had sex Valentine’s Day and last weekend. (2 weekends in a row). So my friends are telling me I’m having pregnancy symptoms and that I should take a test. No I don’t usually feel like this, my “period” is supposed to come in 3/4 days. Also, since I’ve been on the pill, I don’t really get period symptoms anymore. I’m telling them I haven’t missed a period yet so I don’t need to take a test. But they think I should...what should I do?
