Could i be pregnant

Hey, I've not been on glow long, but me and my boyfriend have only been TTC for a couple weeks. I had my implant taken out on the 9th of April. We've had unprotected sex nearly everyday since. I haven't had a period yet either...

I've been pregnant before but sadly miscarried at 6 weeks with a different guy. So i don't remeber any significant symptoms ...

I have graves disease and hyperthyroidsm, recently had my thyroid taken out and im on medication to replace it but dont think that affects anything..

I guess what im asking is...

Is it possible to be pregnant already?

When is a good time to take a pregnancy test, as from being on the implant my periods were irregular?
