Hi Jen!
I had exactly the same problem, arg! I am now 28 weeks pregnant and finally seeing a change for the better!
I stopped using my regular product (RegimA) and started using a Rooibos tea scrub (available at Clicks, P&P etc), and every evening I also make a cup of plain rooibos tea (no milk or sugar), let it soak and then once it's cooled down I wipe my entire face, back and arms with the tea using a piece of cotton wool. I don't put any cream on in the evenings, only in the mornings - that way your skin can dry out overnight, which helps fight the acne. It;s also good for scarring. Sometimes I even wipe my face with the tea in the mornings before I put cream on. Oh, and I also washed my back with the facial scrub in the shower.
I've been doing this for a few weeks and I can really see an improvement now, finally. I also read that it's important to drink a lot of water.
Good luck!
