Today I am 23 weeks pregnant and am trying to work out when I conceived, I have tried all of the conception apps but they all give me a different range of dates. I have had 2 scans which I assume were taken from my LMP but I’m not too sure when that was? The doctors have told me it was the 13th of November but is there any way to be sure?? It could have been anywhere from the 10th to the (20th so just looking for a bit of advice as I think my due date, the 19th of August may be wrong.. this is my first baby so am looking for a bit of advice ☺️ If last had sex on the 16th of November with my LMP and due date could this have led to conception?? Thanks x
