:-(Hi. My name is Kayla, well this is my situation I have had 3 misperiods but negative pregnancy test and it is really driving me insane. I always did have a regular period and it would come on every month around the same time. During my last period though i noticed a change, I would usually cramp and be constipated but on my last period i was cramping or constipated and plus my menustration would usually stay on 6 days during my last period it only stayed on 3 days. I dont understand this situation I am so worried because i never had these problems before. I just want to know what could be wrong with my body. during the 1st month and a half i would puke everyday, I am constantly catching headaches,my abdomin is getting a lil bigger and my pants are getting tight, i get tired frequently,and aggravated,my breast are getting bigger and darker and swollen sometimes it hurts me. Like all of pregnancy symptoms i catch it. Someone please help.
