Anyone get pregnant with the pull out method?

4 month pp and not on the pill. We have been using condoms but a week ago hubby just pulled out when we did it. Well turns out I was ovulating then. Now I am super nauseous and having tons of pregnancy symptoms. This happened both with my son and when I had my miscarriage. Both times I had nausea at 7-8dpo, tender breasts.. I 100% knew I was pregnant both times. I’m really starting to worry. Babies are blessings but I am definitely not ready to have #2 quite yet! I have a cyst that has been wreaking havoc on my body, causing PAINFUL ovulation and periods, not sure if it can cause nausea or if that can be hormonal.. looking for some insight!?
