I am 34 years old and have always had a regular cycle lasting 28 days with a 4-5 day period. This month I had a regular period and then 3 days later BAM back to bleeding like a regular period with awful cramps. Then the bleeding stopped and again 3 days later now I am bleeding again. This has never happened to me before. I was on fertility meds back in may but haven't taken any since then. Has this ever happened to anyone????
