Hi Dr. , my last period was on June 9. My husband & I intercoursed on June 21 (during fertile window) and July 1. At the same time, Im also fasting for this ramadhan. My next expected period supposedly to be last Sunday, July 6. It did not arrived nor do I have any symptoms of it coming. Unusual. My nipples hurt, which is also very unusual. I tested today (cycle day 29) afternoon with clearblue compact but negative. Generally, im quite regular 27-28 days. I would like to know if fasting affects my chances of conceiving, or should I test in a few days time? Please advice. Thank you.
