After the bleeding stopped completely, I waited for a month and got my first period, which seemed very normal, no pain
, no problems, maybe just slightly on a lighter side. Then, to my complete surprise, I got another period only 20 days later. Usually, my cycles are 30 days apart, but this time it was a 20 day interval, the period is slightly heavier and I wake up in the morning with a mild backache. Is this normal?
