Not sure if pregnant or just a hormonal imbalance?

Hello Ladies, I’m new in this group. Gusto lang po himingi ng payo, TTC po kmi ng husband ko at this time super late na po ng period ko, last mense Oct 2 pa (every month po ako nag pe period pero hindi lang sumasakto sa araw, madalas 1 week late than usual) Last check up ko po sa OB ko is Sept, had my ultrasound to check if normal uterus (normal naman po, sabi sakin, it’s just a matter of timing) Pero almost 2 months ba po akong walang mense , negative po ung PT nka ilang test na din ako, pero i feel like there are times na nakakasuka ung mga kinakain ko. Im not sure what to do. Or baka acid lang po ung nararamdaman ko. Thank you for your answers! May God Bless you all. 🙏🏻
