after shaving I get razor bumps??

I finally figured out how to keep my lady parts razor bump free after the initial shave and a day after. However about 3 days after my skin was getting irritated just from he pickle hairs growing back and I was wondering if anyone had advice?? I'm on my peiod so I'm sure messing with tanpons and stuff down there hasn't helped but should I just keep applying the bikini zone cream on my skin down there everyday?
