Not sure! Need help!

Breanna • Hi! My name is Breanna. I live in Oklahoma. My husband and I are trying for baby #2! Our son just turned one!
Okay so on August 13 I had my Implanon BC out on August 15 I had a cycle that lasted 4 days. I have had all the symptoms of AF to show up like night sweats, nausea, some slight cramps, back aches, cry over literally everything (ridiculous) sore reast off and on, no energy to do anything! I have taken 2 test and all BFN.. Don't know if i should wait a couple more days and test again or AF is just weird cuz I just got my BC out??? Please tell me your thoughts!! Also CD 33 and DPO 14 and AF is 2 days late
