TTC need help.

My fertile window was June 1st-5th June 3 was the highest day to have sex. Now it's June 12 and I been experiencing my boobs getting a tad bit bigger, sore boobs and nipples for about 3 days now and just starting yesterday I've been getting pelvic pain on the right and left side and cramps that feel like cramps if I was on my period my period not due until the 19th and the app says I have 5 more days till I should take a pregnancy test. Just need input if this could possibly be early pregnancy signs or what ??
