Am I pregnant??? (Read fist)

Hey girls, i am wondering if i am pregnant, i am married just in case alot of you start saying “ you shouldn’t be having sex if you are asking this dumb questions “.... okay so i woke up today around 5 am when my husband was going to go to work & I feel sooooo dizzy i had to run to the bathroom and i trew up 3 times, this has never happened to me before so i dont really know whats going on. I was checking and if i am pregnant I would be 3 weeks today, any thoughts? What so i do? Take a test? Or wait for my period which is in 9 days??? Btw i have been felt like this aaaallll day 😩
