Hi Mrs N - thought I'd add my own thoughts if it helps?!
I started drinking a carton of grapefruit juice the week before O.
I took Oil of Eve Primose Oil until O.
I used pre-seed on all days we bd'd apart from day of O
I used my mooncup after sex (to keep the sperm in!) and lay down for like 20 minutes with my legs in the air
Every time we bd'd he was on top and I was lying down
Here's when we did it this month (DBO: Days before ovulation)
dbo7, dbo6, dbo4, dbo3, dbo1, day of ovulation
Also - i started back at the gym week before ovulation to improve my wellbeing and made a special effort not to get stressed or anxious (very hard I know!).
My period is due tomorrow, and usually I am spotting at least 2-3 days before. I have had no spotting at all and my cervix is feeling very tightly closed. I am being realistic and not getting my hopes up until I see those lovely two lines. But as my OH is going away next month I wanted to do everything I could to get a BFP this month. Fxd!!
