Pls answer help

Does anyone know how to tell if their tubes are blocked? I’m really scared mine are... I’ve been trying to conceive for 4-5 months. I got an ultrasound yesterday and they said I ovulated 2-3 days ago and they saw the corpus luteum. I get ovulation pain and sometimes it hurts when I have sex it just might be what position I’m in but idk it doesn’t hurt every time I have sex. PLS HELP!
