Malou
This cycle has been a little off, I had my period on Oct. 12 which lasted 4 days. It usually lasts 6. I ovulate 15 days after my period ends, therefore I estimated ovulation on the Oct 31. I ovulated Nov. 6 which is kinda late since my period is due on the 11th of November. Has any one ever gotten pregnant 5 days before their period is due?
