Thanks for you support ladies,
well doctor took my blood pressure and listened to my heart which he said sounds normal. The palpitations could be the baby laying on a nerve or beacause your fluid level is up 40% when your pregnant it could just be my heart trying to cope with the extra fluid.
Either way he has signed me off for my last week at work which i thought he would anyway so i can just chill out now and not have to worry hopefully that will help.
Lea i would make an appointment and get them to check your heart out as thats how i felt like i was going to have a heart attack but dont last very long, think i worried a bit more as i am a bigger girl anyway i was thinking the worst.
