When can I test? And can I be pregnant? R

When I ovulated I had sex almost every day Like every other day. I was suppose to start period today. There's nothing. Not even when I wipe. I feel like I'm going to puke but haven't yet. I keeping burping over. I feel really iratible. I cried today on something that my so did

We are moving into a house

He his painting it. And he showed his dad it whem I wasn't there. When I found out tonight. I cried right them and there. I've been crying like that off and on and my mom said that's not a reason to cry. Been very emotional. Ideas? On if u guys think I'm pregnant? And maybe what symptoms every body had. And a cording to glow u was suppose to start today. Didn't

When can I test? Also kinda dizzy and tired. Got a little head ache. That all. Thank u
