I stated clomid June 28 to July 2, I was suppose to ovulate on July 4 according to ovulation calendar I do on webmd, but with taking the clomid it pushed my o date back to July 8, so I am wondering if that will ppush my period start date take back further to. The calendar that said I would ovulate on the 4, also said I would start on the 18, which today is the19 and it hasnt happened, just very anxious!!
