Pregnant by 4 days before ovulation?

Any one of you lovely mommas get pregnant by 4 days before ovulation? I'm not pregnant but TTC for 10 cycles now and my husband works offshore so it's very hard to get pregnant. And he mostly always leaves right around fertile week. So I was wondering if y'all had any experience or had a friend that baby danced 4 days before ovulation and got pregnant? Thanks so much in advance!
