Hi, i'm normally on time every month, except last month i was probably 3 days late and then had HORRIBLE cramps then started bleeding!! Probably the worst i've ever had. I was running when it happened and I literally dropped to the ground and couldn't move. Then this month I'm late again, six days late, but ive been spotting the last two. Very very light spotting. Doesn't even show up on my underwear just when i wipe. I'm so confused? I took a prego test and it came up neg. So im lost? Anyone have an idea?
