My last cycle started August 24th, 2017. My doctor says my due date is June 28th, but I measure farther along than that. She says the conception date was on October 5th. This does not make any sense to me as my last period was in August. Also, my husband and I did some experimenting on October 14th. Based on this information, when is my date of conception?


If your LMP was indeed on August 24th, then based on that your fertility window may have been between September 3rd-September 13th, with a possible due date around June 1st. Was there a mistake and she thought your last period was in September? If your last period was in September, then I could see how she might think you conceived around October 5th.
