First time! Need Help!

Hi, im not to good in english but i do the best i can.

My period should start in dec28.. 2 weeks earlier i have pelvic pain, but my period didnt start. so far today i have 10 days of delay.

My boobs hurt and so much sensible! But i have like pelvic pain.. not to much but i have it since one week, i go wc reagulary and i sleep much.

This is my first time this happend to me, im very regular, but im afraid that pelvic pain is something bad. What do you think?.. should i try a test or should i wait?

Oh and i almost forgot on january 11 it would be exactly one month i have relations on my ovulation day.

And this syntoms are normal?

Thank you!!
