This is the second time this year that I've have two periods in one month. The first time was earlier this year and I went to the doctor about it. She told me we're "allowed" one weird cycle a year. I just finished Sunday before last but started bleeding again this past Wednesday. I always have a full 7 days for each period and this one seems as regular as any other time, besides the fact that I just had one. No pain. It's more annoying than anything. Should I got to the doctor?
