I'm a 19 year old nursing student and would hate to be pregnant right now.

I have been on Nexplanon since March and have not had a period since.

My boyfriend and I use condoms and one broke 2 weeks ago.

I got STD tested and he did too and we are both still clean.

Is it impossible for me to be pregnant?

Or get pregnant? He did ejaculate in me.

Does it even pay to take a pregnancy test or is it a 100% no?

Thanks much!
