Pelvic pain

**PLEASE HELP** me and my boyfriend been TTC for about a month now and last night my pelvic was hurting. This morning i woke up to the left side of my pelvic acne not necessary hurting just irritating. I dont start our lovely girl time till the 26th. My boyfriend my nipples feel weird but i dont think so maybe it just him getting excited. I dont know any symptoms or what to expect it my first time TTC.
