Plan b and late period

I had my las period july 3rd-8th and had unprotected sex - he pulled out early like i watched “it” come out not inside of me- on the 9th but i took a plan be literally less than an hour after. Ive continued to be sexually active but have used a condom every time and neither one of us have ever seen it be broken.. is it too early to freak out? I know plan b’s can make your period a little late but idk how. I dont feel pregnant but i just want my period.. also im having period symptoms such as sore boobs and breakouts like i slways do before my period just no blood yet.
