I had dark spotting and was really worried (being that this is my first pregnancy) so the doctor sent me along for a scan. Everything was fine, but we weren't as far along as we had originally thought...Only 5 ish weeks, and only a sac and yolk to show!
The tenderness of your boobs will change from day to day sometimes hour to hour. I haven't had what I would consider morning sickness as I haven't been sick every day. Perhaps, only 9 or 10 times in the last 2 months. Its just feels odd sometimes, when you have those times when everything seems normal and you question whether you had just woken up to find that it was just a dream...But really it isn't.
I'm sure that everything is fine, just take things easy and look after yourself.
