I am recently off the pill after 10 years. I started years ago due to irregular periods. My last period started on May 19th and right after I started using Opk strips because I knew my cycle would be off. After weeks, of negative results on June 20th I felt the pain in my lower right side. I knew that was ovulation and sure enough I tested positive on the strip. It is now 15 days post ovulation. I took 3 pregnancy tests one 11 days post ov, one 13 days and one today. All negative. I have been feeling slight cramping for the past week and even pains in my legs. However, no period. My dr. informed me that I would get a period in 2-3 weeks from ovulation and if not that means I'm pregnant. Could I just not get a period at all and not be pregnant? Please let me know. Any information would be helpful because I am so worried and my dr. is out of town. Thank you so much for your time.
