I know this is all very hypothetical but...

If I were to plan to have a baby in late September 2018, when would I need to conceive?

Sometime around new year. I was due late September with DD1 and am pretty sure it was around then.

I had my BFP on 17th January and was due on something like 28th September.

Ok thanks. Another question sorry...did you drink in the tww?

Yes definitely during the festive periods. I've two nieces that are late September babies due to a few too many eggnogs

Haha that's great thank you so much!!! :)

We're due 20 sept, we conceived Christmas Eve, OH was ill from Boxing Day onwards for about two weeks so I definitely know it was then haha

Haha awesome :)

DS was born 23rd Sept (but late, was due on the 9th) - conceived Dec 19/20th, BFP 4th Jan. BUT this was after 18 months of trying, so the timing was not planned at all, I was just happy to finally be pregnant!
