Pregnancy Paranoia😅😖

I need advice because I'm having some MAJOR pregnancy paranoia.

Throughout this month I haven't been on my usual birth control (Nuva Ring) because I no longer have insurance to cover it. Financially I can not afford condoms at this moment.

I'm very active with my husband and we are both very cautious when it comes to not getting pregnant. Every time we have sex he pulls out 10 seconds before he cums. In other words he finishes himself outside of me.

I know pre-cum exists and that even that can get you pregnant. Should I be concerned? Will I still get pregnant even though he ejaculates outside of me?
