Terrified.. need help

Well I’m convinced I’m pregnant. My period is due tomorrow, but I’ve been having symptoms for the past eight days. I had protected sex on the 17th, probably 4-5 days before ovulation. He didn’t pull out but he wasn’t deep inside me. We checked and squeezed the condom after, to see if it was leaking, and it didn’t seem to be. I have really bad anxiety about this because I’m only eighteen and don’t know what to do. It’s with my serious boyfriend (who I plan on marrying and spending my life with.) I tested on Friday and it was negative, and I plan on testing this morning so I’m just super anxious about it. Only him and one of my bestfriends know.. but when I’m not with him... I’m so lonely... and scared.

Update: took a test today (jan 5th) and it was negative. shortly later I got severe cramps and my period! scare is over :)
