Passing out???!!!

L • 26, due with 🌈👶🏻 August 7th

So I’ve been TTC for 7 months as of now. I am 2dpo so hopefully this is the month. Yesterday I was feeling really dizzy and passed out in my kitchen. Today I’m feeling just as dizzy and feel like I could pass out any moment. Is this something that usually happens following ovulation when progesterone spikes? I know it’s too early for pregnancy symptoms so is this something that could just be caused by my normal cycle? I’ve never had this happen.
