DTD ? settle something for me

If you are ttc, but not swaying what is the best way to get pregnant.
On another site someone and I are having difference of opinion.
We were both giving advice to someone else and
I said it was best to DTD every 2 days, she said it's best to DTD for 3days straight around 0.
I said I read it's best every 2 days cause it gives the sperm time to be mature enough to fertilise the egg, then she said that her FS during IVF told her it's best DTD every 2 days from CD10 until +opt and then DTD everyday for 3-4 days.

This has the OP confused and she said now she isn't sure what she should do and the other girl said just do what she had advised cause it's the correct way cause her FS told her so.

Not sure if anyone really knows the answer to that question (may be unique to each couple anyway) but this is a good method and the one most commonly used for TTC. Sperm Meets Egg Plan
