Conception

How do you work out due dates/conception dates?

Asking because there is a possibility I may be made redundant due to department closures at work. The earliest I would have to actually leave (after serving notice) would be 31st Dec.

We are ttc, and I have read the maternity policy today. To qualify for maternity pay I need to still be employed by the "qualifying week" which is 15 weeks before my due date (so, presumably 25 weeks pg).

How do you count the weeks? When is the start of pregnancy measured from, is it the date of ovulation on the cycle you conceived, or is it a date related to your periods?

I think we're ok to keep trying for this cycle and next, and then will have to see what's happening at work.

Bloody job!

"think" was of course supposed to be in italics, not bold

Pg is measured from the first day of last period.

Have a look this because it tells you how many weeks you'll be on any given date with no faffy counting of calendars

Just to add, we've just started ttc now and if we were successful this month, due date would be end of Jan.

Am I taking over this thread?

Cheers Rock.

So if pregnancy is measured from the first day of your last period, then actually you're only pregnant for about 38 weeks? (assuming ovulation on about day 14). I thought it was counted from your first missed period rather than last one that happened.

This is good, may give us three goes rather than two!

Yes, the first two weeks of pg aren't really, so on the day you conceive you're already 2 weeks pg
