Questions??

So this is my first baby. I turned 7w today and according to glow I should be due anywhere around Aug. 21st. I was just curious about other people's morning sickness. I have not thrown up yet...thankfully...but I am sick and nauseous all the time. No food sounds good,although I make myself eat. I've had mild almost period like cramps on and off for the past few weeks. I spoke with my doctor and he said I shouldn't be worried unless I'm bleeding which I'm not. I have my first app tomorrow morning, I'm just curious if anyone else has felt this way. I have pcos and I've read things and kinda worried myself a little and I just wanna make sure that this sounds normal. I feel yucky all the time.
