I know how you must be feeling, the worry of not knowing is so hard.

I have never really experienced nausea with any of my pregnancies. I had a slightly stronger sense of smell, but could still handle cooking meat etc. Re my boobs, I really wouldn't say they are sore. It is hard when for many being pregnant is defined by how bad your morning sickness is. But I wouldn't worry too much at all (easier said than done I know)

I'm currently 5 weeks pregnant, my breasts feel slightly fuller (but this is No 4) but other than being more tired than usual and having really weird dreams I don't really feel that much different.

Good luck for the 7th of April, I'm sure all will be fine.
