Crying randomly when emotional

Hi there! Any mummies here will cry more easily when preggy? I will suddenly cry & sob when i feel overwhelmed. Currently 24 weeks & i tink i cried like 4 times suddenly. Once when i'm having flu & feel so sad my body is sick. Then twice when i'm just too tired & feel like i dont have enough sleep. Last was when hub say someting i can't rmb now then i just cried.
