Why is it so hard to switch off??? I have another 2-7 days before my next period (I'm irregular) and I badly want to be pregnant!

Last night was the weirdest one - I was fine apart from mild sore breasts and other small bits and bobs but all of a sudden I became light headed and felt so sick. I spent over half hour sat next to the toilet. I was so hot! I didn't be sick but after a bit I managed to get into bed and I felt better. Iv been ok today! Odd. Tonight iv been having hot flushes and headache. My boobs are only a bit sore with random feelings of being on fire.

Ahh I'm trying to forget about it but my head isn't letting me!
