I NEED YOUR HELP

Alright, when it comes to the idea of even having children I’m terrified. Last Friday, the 14th of October I had intercourse we didn’t use protection which is the first time in ever we haven’t. He didn’t ejaculate inside of me and I made sure I wasn’t ovulating ( my ovulation ended the 9th), my last normal period was September 21-27. I took a test Friday October 20th because I’m a paranoid person, the text came back negative. My period is due today and I haven’t gotten it, it’s only 12:00 but I’m still very worried. I’ve had an unregulated period for quite some time, I’m currently taking zpac for a double ear infection (i have been taking it since October 18th) and fluconazole for a yeast infection (I started today). Am I just paranoid or am I pregnant and it’s just too early to tell.
