Hello!
Haven't checked in for ages as been feeling so rough and exhausted.
Have constant nausea, but without the throwing up. Every time I eat, it soothes for about 1 second and then wham back to feeling hideously nausea. Nothing seems to help settle it at all. Have gone off loads of food, and nothing that has worked in previous pregnancies has worked this time round. Wails! Am hoping it will wear off soon.
The toddler has noticed that I am constantly eating (in bid to ward off the nausea) as said to DH "Mummy eating lots!" 
DH nearly gave it away to DD this morning, as she tried to grab me and give me a big bear hug before I left to work, as he went "Mind Mummy's tummy" to which she looked very suspicious and went "Why? Are you pregnant?" to which I hastily scoffed and went "NO! Don't be daft, just got a sore tummy" whilst apologising to baby in tummy in my head that I was lying to his/her big sister!
Am burping constantly and my goodness am salivating loads! Don't recall burping and excess saliva in my previous pregnancies.
One of my friends has clocked that I am pregnant, as was a bit difficult to hide, as we went camping with them last week, where I spent much of time sleeping due to sheer exhaustion, and then looking like death warmed up due to feeling nausea constantly.
On the positive side I have a date for my dating scan - 28th August. Looking forward to seeing the little one wriggling around.
