Calculate due date with no AF Q?

I need help ladies.

I have not had a period since before my DD was born - 2005 to be exact as I have been BF since.

We are thinking about trying for #2 so how is the doctor going to calculate my due date with no AF since 2005! I know they can go by the sono measurements but will he need to know the day we did the deed

If we did manage to cocieve this week would I have a september or october baby?

Sorry for all the q's...DD # was a suprise so this planning stuff is all new to me.

TIA

Re: Calculate due date with no AF Q?

if you aren't menstruating how do you know you're ovulating? are you using OPKs? just curious...

they can calculated your due date pretty closely using sono measurements. a friend of mine hadn't menstruated in 3 years because of PCOS, but she ovulated one month and got pregnant. she gave birth very close to her estimated due date.

if you conceived this week, your due date would be about 38 weeks from now. check out this calculator:

I dont know I am ovulating...I have no idea what is going on in there...figured we would just go for it and see what happened!

Should I be checking for ovulation?
