I was thinking about my timing mostly. You see I was having a hard time pinpointing O. I would get a +OPK but then my temp wouldn't go up for a few days sometimes. Well, the same thing happened the cycle I conceived this baby. But luckily I had decided to just BD every other day instead of just on O day. Before my 11 week ultrasound I had assumed I O'd late and was probably really due on Saturday or Sunday and not on Friday. So I was surprised when the ultrasound measurements revealed that I probably conceived on Thursday and was actually measuring 1 day earlier then my LMP due date. I'm including my chart so you can see what I mean. I suspect I really did ovulate and conceive on the day I got my OPK, which was CD14 or April 17th.
My whole attempt was pretty much based on the timing. I did use preseed and propped my hips up. I was trying to follow the boy diet and doing some supplements (I think? Don't remember which ones). And I took soy isoflavones CD 2-6 that cycle only. But after my two miscarriages and months and months of BFNs I decided I just wanted a BFP. I know if this ends up a 4th girl that I will be a little dissapointed in myself that I didn't do more, but oh well. I was also relying on astrological moon sign, since it was right for all of my girls. It was a masculine sign but it wasn't quite a full moon (3 days before). My pH was at a 6 the last time I checked before conceiving and DH was a 8. Don't remember what else I'm supposed to add.
