You really do sound very stressed Sheryl. It might sound ridiculous to you now but try not to get so worked up and stressed as it won't help anything. Lots of people bleed a little bit in the early days. In fact I remember my own sister bleeding off and on for five months! The fact that you're snappy and tearful could be put down to stress or it could just be that 'before a period feeling' - difficult for you/us to know at this stage.
Hope it goes to plan and you are pregnant but even if not then there's always next month and all that fun you can have trying...

(I can remember wanting to slap people when they used to say that to me as we all know when a woman wants to be pregnant, she wants to be pregnant THIS month and NOT NEXT!

)
Thinking of you as we all are and crossing fingers too...
