Could I be pregnant?

I took a plan b on either Friday or Saturday (he came inside me 5 times in total the first 2 days) we ended up changing our minds- we want a baby, so he came inside me again on the 14th and 15th. Obviously my period is close but I’m not feeling the “early symptoms” like I normally do. Am I missing my period because of the plan b? Or possible pregnant? Or is it just me..

>>>>NOTE: I messed up the Plan b and it basically melted in my mouth because I didn’t have water. <<<<<<

Edit: we’ve wanted a baby for 5 years but there was a threat of me having to move quickly for work but we found out I could stay on Sunday and didn’t have to leave, the baby wasn’t a quick decision. It was in our plans but something came up.
