I had my last period Oct 31 for a day . No period in Nov. Im on Pill and I forgot to take It twice but doubled up like they say. No period in Nov. I took a pv test and it was neg. I took two more one did not have an answer the data other neg. I have 3 kids already. My concern is stil no period but somr pain on right side here and there. I go to my obgyn in a few days.
