I need help

I know this sounds stupid but I worry a lot. The last time I had sex was may. I had my periods. Me and my boyfriend still finger and do blowjobs. Sometimes I get scared I can get pregnant from that. We are carful but I still get scared. Could I get pregnant from this. We stopped having sex because we decided we weren’t ready and we stick to foreplay. It still scares me and I feel sick in the mornings. Could I be pregnant?
