Implanon Removal & Pregnancy

Hi ladies,
So I had my Implanon out at the start of May after having it in for only 8 weeks (long story!) So me and my fiancé began ttc straight away and a day or so after removal I'm pretty sure I had ovulation pains. It's been 3 weeks and no period. 
What do you think I should do? wait and little longer than test? Any experiences or opinions would be great! 😁
