Breastfeeding and ovulation

Hi all!! I’m currently 10 months post partum. I was EBF for about 6 months I’d say and now I still majority BF but I do mix with formula as well. I have not gotten a period which I know is normal (with my first I never got it until I stopped BF). Based on certain things, I think I do ovulate here and there but not regularly. My husband and I did the deed last week 2x and I’m having cramps & symptoms I did when we tried for my now 10 month old a week post sexual activity. Am I just crazy? Anyone got pregnant while BF?

Thanks ladies!!
