PLEASE A MOMENT OF YOUR TIME !?

Cassaundra
My husband and I have been TTC a little less than a year and we tried a the day before and after ovulation and 3-4 times a week normally . 
​My breasts have been sore and I was due to have my period July 11th I got it today 6 days early .
​I ALWAYS get my period the 28th day today was the first time it was 19 days! Also this bleeding WAY different ! It's ALOT lighter but cramps are horrid and my back is killing me !!!! ?
​I read bleeding irregularly when you never have is an early sign of pregnancy . Am I crazy or does it sound like I may have become pregnant ?  
​What should I do ?  When should I take a test ? Should I take one ? 
​Any help ? 
​Thank you !!!
