Hi there girls! I just wanted to help put your mind at rest. I did loads of pregnancy tests with both of my children. I also had to have an early scan with
DD as i was spotting for a while and they wanted to make sure all was fine. Which it was. We could see our little 'Button' on the screen with a tiny flickering heartbeat

However when i went for the Standard 12 week scan i was still convinced there would be nothing in there even though i had already seen the baby

I didn't have to have an early scan with
DS but again at the 12 week scan i still thought, maybe i have imagined it all, and i am going to look so silly when they say:- 'errrr you aren't pregnant!' lol Still, again there on the screen was our little 'peanut'

All i can say to you is in my experience (and most of my mummy friends experiences)it is completely normal to feel this way.
I really hope all goes great with both your pregnancies, congratulations to you both and fingers crossed in 9months time you will both be cuddling your beautiful little ones! Xx
