Hi all! 
This is our first month of TTC. I can't help but pick up signals that I could be pregnant! I have had lower back ache for a few days (but got worse yesterday and today) & I have never noticed that before. I had what I thought was my AF on the 11th as it was a medium flow but on the 12th (yesterday) it was hardly anything, like how it is when it's finishing and today it has completely stopped! I always have 5-7 day periods so this is very unusual for me. Could I possibly be pregnant?
