I had my implant birth control taken out on January 14 2014 and had unprotected sex on the same of it being removed and then again on the 15 and got my period somewhat heavy on the 16 and now its gone and today is the 19 is there a chance I could be pregnant

Any time you have sex there is a risk of pregnancy as no form of birth control is 100% effective. You are now playing the waiting game and have to wait to see if your next period comes as expected. If not, wait until it is 2 weeks late and test using first morning urine.

Can I take a test early?

You could, but you risk inaccurate results, such as a false negative. Why waste your money?

How early could I take one that it won't be false

Two weeks after your missed period.

Thank you for your help

You see, it takes time for the pregnancy hormone, hcg, to build up in your system to where it is a detectable level. The first symptom of pregnancy is a missed period. Sometimes periods are late, even for the most regular of women.

Unfortunately you are in the hurry and wait scenario. Stressing too much will cause a late or missed period.
