yesterday while out grocery shopping i had a dizzy spell, and felt like i was going to faint. this morning i felt fine until this afternoon where i felt dizzy again, and decided to try and sleep it off. i slept for about an hour and now i’ve woken up feeling worse. it’s been approx a week since i ovulated, and i had sex prior to that. i’ve also had sore breasts, and i’ve been very hungry/“blood-sugary”. could this be an early sign of pregnancy, or something else? thanks x
