Pregnant on nexplanon?!

Estrella

I’ve had nexplanon since October. Me and my boyfriend have had unprotected sex since then. He’s obviously done it inside multiple times. However 4 days we had sex again(unprotected) he did it inside. Today I had a horrible migraine w/ nausea. The past days I’ve wanted to pee more but I’m currently on an hsv 2 ob also. Could I be pregnant? I’ve heard so many stories of women pregnant on Nexplanon I’m freaking out.
