pregnancy questions

i get my period at the very end of each month and it leads into the beginning of the next. i’ve already had my period this month and had unprotected sex while i was in my fertile stage. at first i was sure i was pregnant because i was feeling so many symptoms, but the last four+ days i’ve felt fine, so i thought i had just been freaking myself out and wasn’t pregnant at all. it’s too early to test anyways. my period is still 10+ days away, i usually get PMS symptoms four-five days before my period begins but today i’ve had the most intense period cramps in my lower stomach and back. my mood swings have been pretty bad, the past couple weeks i’ve been way too tired. to anyone whose been pregnant before- did it feel like period symptoms? i’m just confused because all the pregnancy symptoms went away😕

update- i’m so freaking bloated it’s crazy. these cramps are so horrible and still haven’t gone away and i’ve had a few sharp pains in my actual vagina but they were tolerable. i’m so confused!
