9dpo symptoms???

Mara
So I'm 9dpo and I am CRAZY tired!!! I'm a stay at home mom so I haven't been this tired since my son was a new born. But for the past few days over the weekend my fiancé let me sleep in and I didn't wake up till 11 and 11:30 each day which is rare for me the latest I sleep is usually around 8-8:30 and also today he let me sleep till like 10:30. I've been so tired that I actually fell asleep for a few hours this afternoon which hasn't happened since my son was a new born yet again. My boobs have been slightly sore that it's barely noticeable so I ml not thinking of that as a sign yet. I have also been super gassy this past weekend into today...  Is it still too early for symptoms or not? I know when I was pregnant with my son I was very tired really early on but I'd like some advice and opinions please if you don't mind. Also my back has been killing me and I've noticed a few things smell stronger and or a little different than normal but it's mainly the tiredness that's getting to me and throwing me off.
