Im 23 and when ever my period comes around i get extremly weak to were i feel like im going to pass out but i never due. I began to feel like a groggy feeling through out my whole body. I can't even leave my house it gets that bad. I also feel very out of it. It only happens a day or two before my period and last all throught out my whole period. It has been going on for 6 months now, also my period blood is very runny. I have been bleeding extremly heavy as well! I have always been a heavy bleeder but it has gotton worse of the past 6 months i have to change my pad every half hour or sometimes every 15 min! I have had a blood work done, cat scan of my ovaries with the dye contrast, and a patsmere the only thing they found was a ruptured ovarion cyst that was really tiny like 0 something centemeters yet they didn't know when it ruptured. My gyno looked at it and said it will go away just leave it alone. Can this be the cause of my problems with the weakness? I feel like for 6 days out of my life im paralyzed! How long does it take for a cyst to just dissapear it has been 6 months already! i just went to the gyno last month and thats when he told me to leave it alone it will eventually go away. Or does anybody else feel extremly weak on their period.
