Hello, Thanks for writing to us. I have gone through the query and understood your concern. Home pregnancy test usually reads well two weeks after conception, at least. This implies that you may have conceived during the first or second intercourse date mentioned. Since the rest are very close to the date of the pregnancy test, and presuming you have a 28-30 day cycle, the earlier dates seem more likely. The emergency pill was consumed within the stipulated time and this should have protected the first one. You can correlate through the trans-vaginal sonogram to determine the gestational age, which is less erratic in the early days. Hope you find this information useful. Take care.
