please help

i lost my virginity about a month ago, right before when my period usually starts ( he wore a condom but i’m not on any other bc) .. I had a period two days later, but it only really lasted 3 days and was lighter than usual, and mine usually lasts around 5 days — it did fill up tampons/pads though.. it’s time for my period now and i’m not sure if i’m just freaking out but i feel a lot more emotional and cramps are there but very mild. My lower back and boobs are sore, which is a good indicator of my period usually but i feel like it’s taking too long.. I’ve been freaking myself out looking at early pregnancy symptoms but i feel no nausea at all and i’m not experiencing any spotting. Was my period maybe implantation bleeding? should i take a test??
