3DPO and sick

anon • 🤫
Hi all. I am not one for early pregnancy phantom symptoms but things have gotten so odd.
This month is had terrible ovulation pains (i usually get some but this was super intense!) and i am now 3dpo i think and have just been sick. I am never sick. 
I feel off key. Like tired, nausea, thirsty and just not right.
I think i am pregnant. And that's not happened before in the 8 months we've been ttc. 
I know it's super early but sometimes don't you just have a feeling?
I was wondering if anyone had gotten any obvious pregnancy symptoms early on or kind of just known they were...
I know i could just be sick but i wanted to ask for advice as I just feel different. 
When i was pregnant a few years ago i had incredibly bad morning sickness from early conception all freaking day and it went on and on. But, i didnt feel pregnant. I am so confused right now! Help!
