I Am A Female 24 Years Old 116 Lbs And

I am a female 24 years old 116 lbs and 5 ft 3 inches. I have been having issues with my menstrual cycle. With it being pretty much nonresistant. It only last at most two days and is only there when i wipe very light pink. This started when i had a stillborn in 2011 and has been this way even after having my second child in 2012. Along with this I am always fatigued my muscles constantly ache and my skin is hot to touch all over and I am not running a fever of feel uncomfortable. I had an ultrasound on my thyroid said had some fluid, but seemed fine for me. I also had in Oct of 2014 an ovarian cyst rupture that i had surgery for. Along with removing some endometriosis. I have also been trying to have another baby with no such luck.
