hi ladies, so i have a problem and i'm just wondering from other soon to be moms or even nurses / doctors on here what it could be! 

alright, so i never skip meals. typically this has been happening to me in the morning after breakfast. i've had this happen maybe 4-5 times total during my pregnancy but also have had a few before my pregnancy as well. so about 30-45 minutes after eating i get what i call an "attack". i start to get really sweaty, and my stomach starts to ache. it quickly turns into blurred vision (or i start seeing black blotches), i can't form words out loud and my heart races. i've actually fainted once already from it. after an "attack" i feel incredibly weak and tired. i'm just wondering if anyone knows what this is? my mom suggested a panic attack, but i've had one of those before and i don't think it is that. i see my doctor on Tuesday and will definitely bring it to his attention, just wanted to see what other moms/ medical professionals think it may be. 

thank you ladies!
