I m 45 years old, trying to conceive on Clomid . My periods are very irregular as I m premenopausal. I ovulated on 7/26/12 and had relations for 2 days following. A few days after I started feeling extreme exhaustion, had some hot flashes, and food cravings . Now I have abdominal bloating, some constipation and low back pain . I have done over 5 home pregnancy tests but all have been negative. I have not gone to my doctor because I was ridiculed when I mentioned desire for a baby at my age. My OBGYN was more open, put me and hubby on Clomid (he had low sperm count after vasectomy reversal and how his levels have more than doubled). Could I still be pregnant? How can I know?
