Is it worth taking a test?

Kierra
I got my Nexplanon implant removed 11/29/16. Got a visit from Aunt Flo on 12/13/16. Ovulation was to be 12/26/16-1/1/17. Had unprotected sex on 12/22/16 and 12/30/16. Aunt Flo is expected to make another appearance 1/14/17. The reason I need assistance is because I have a 3y/o son already. I'm experiencing most of the same symptoms that I experienced before I found out I found out I was pregnant with him. The heartburn, achy back and tender breasts, as well as falling asleep at the drop of a dime, no matter where I am, I've also been dealing with some nausea and food adversions. Being that I just recently got off the implant, is it really worth taking a PT or am I just driving myself crazy?? Please help!!
