With my first bpreg I had no idea, my boobs were tender & getting swollen, but I was partying heaps not trying & when I realised my last period was almost 2.5 months ago, I did a test!

Then with preg before christmas last year I got a +ve OPK on the Thursday & Friday, on Sunday I was shopping with Mum, she was driving & we had to do a U turn, I made her pull over & I spewed, I knew I was preg which was only a day or 2 past Ovulation!

This preg I kind of just felt strange about my body & was waiting for AF to arrive after M/C so we could TTC, but I had an inkling I was preg again!!!
I think you can know immediately!???
