Feb to march was a 32day cycle, march to april was a 29day cycle and april to june was a 44day cycle. I spotted on may 9-11 for 3 days very light didn't need to wear tampon or pad but got my period june 8. My cycles r always 5-6days long with heavy bleeding and bad cramps and they always come at the end of EVERY month. Once may 9-11 came around my body changed and it threw me off. Im trying to have a baby but I dont know when I ovulate. When my period didn't come in may my doctor gave me prenatal vitamins to take. I forgot what its for. Does it help get me pregnant? Can some1 calculate when I ovulate so ill know? It might b to late, I dont know.
