Saskia hunny, we can wait this out together. Im 7dpo as well. The wait can be so frustrating!
As for the tummy signs, i really dont know. Each month there seems to be something that is making me think that this could be it, but then other months i know. Yesterday and today my tummy is not feeling right, and then it sparked a little hmm, this could be good or just AF ready to turn up mighty early, then DH turns around and says his tummy wasnt feeling right either! I think our naughty body can play tricks at times.

If you are using an early detection HPT then you could test in a few days. Each person gets different results, but usually waiting until AF is due to arrive is better *side note* for those of us that can wait that long*
