When do you feel it?

Kellie
How soon do you usually feel symptoms? I'm not due for af for another few days but I've been soo nauseous and tired. I laid down to take a nap today and woke up 7 hrs later!!! I don't even feel groggy,  just sleepy. I'm probably just overthinking but Lord, please let this be it 🙏🤰🏼👶🏻
