Hm… it looks like a variation on seed stitch, which also uses alternating k and p stitches. I would do some checks to make sure you are setting up/alternating in the pattern you are trying to achieve.
First of all, you should be casting on a multiple of 4 stitches. So, two ribs k, two ribs pearl would be 8 stitches (you can use any number of stitches, but the pattern won’t work out neatly or you may have to start every other row pearling2 then knitting2 to keep the pattern). Then, always check to see if the row below is done was knit, or pearled… always knit the knit stitches (that look like Vs) and always knit the pearl stitches (that are pebbly).
So, cast on eight stitches, then k2p2 across. When you turn the work, you should have two k stiches beginning on the row below. k2p2 across. Turn. k2p2 across. Hopefully you should be seeing ridges instead of alternating bumps.
What it looks like you’re doing is working on a multiple of stitches not based on 4. So, if you had 6 stitches co, then k2p2 across, you will k2, p2, k2. From the back, this will look like p2, k2, p2. So when you turn the work, if you start k2, p2, k2, what you will be doing is knitting the pearls and pearling the knits (if that makes any sense). What this will do is give you a variation the seed or moss stitch, which has you knitting pearl stitches and pearling knit stiches.
Let me know if this helped!
