Calling all conception boffins! When is my baby due?

[ShushBaby]

After 7 months of trying and some crazy cycles, I finally got my bfp last week. However, given said crazy cycles, I have no idea a) when I conceived or b) when baby is due. I really don't want to take a digital dating test and panic because it's earlier than I thought- and I am deeply disheartened by the idea of my due date being even a week later than I thought it was! (Going by normal cycles it would be 11th Nov).

Can anyone, based on the info below, shed any light on this? Would be very grateful. Thanks.

My ttc journey:

Cycle 1: 29 days
Cycle 2: 29 days
Cycle 3: 29 days
Cycle 4: 29 days
Cycle 5: 54 days(!!)
Cycle 6: 40 days (!)

Cycle 7:

• EWCM on cd9, cd22 and cd24 (mad)
• Implantation bleed cd29
• faint bfp cd31
• proper BFP cd32
• today is CD39

I think the pregnancy tests only detect hCG from 10 or 11 dpo at the earliest, but it's more common to get a BFP after 14 days. No way of telling when you ov'd really, but as you got a faint BFP on day 31, then a proper one on day 32, let's assume you were 14 dpo on day 32 ie 4 weeks pregnant . So you are now 5 weeks pregnant. Only way to know is to have a scan around 12 weeks and even they can be out by a few days.

Congratulations!

Thanks for your reply and the congrats. Yes am thinking/hoping I am 5 weeks.
