Arm pit

Has anyone had or has problems with arm pit odor? I didn't have this problem with my daughter... And this is my 2nd pregnancy and I literally yesterday and took a shower like 3 hours ago and my arm pit still smell and I scrubbed real hard... I just decided to shower again and use my cultures deodorant which is lime lol, I hope it works lol I can't even stand the smell myself.... or anyone knows what else works?
