I am getting a lot more breathless,, i am usually very fit and find it quite annoying.
I first noticed this really really early on (like 8 weeks) when i was lecturing to a group - it was weird, i would be half waythrough a sentence and feel so out of breath - it was very obvious to me, especially as it is the same lecture that i give over and over! One of the girls in the group whole knows me, came up and asked me whether i was pregnant or not as i sounded it because of the breathlessness!!!
The stair are a killer now, but i am so determined to climb them as i am only 15 weeks to and figure i will start taking the lift when i am bigger!
