Yes! in fact this was the first symptom I had with all my pregnancies, even before I had missed my period..a general 'unwell' feeling like a old, sore throat and under the weather.
I think you have been doing your tests too early, missy..if Aunt Flo doesn't arrive next week do another test xx
The reason I tested already is because for a week or so now Ive had that "feeling". My breats have also become tender, bigger and heavier......the weight is actually painful when I take the support of my bra away at night time!!! Also, I still had two periods when I was pregnant with my daughter so couldnt really rely on that. Having said that....I didnt get any symptoms at all with her!
I have another test sitting waiting for next week ! lol
