Spirolactone for acne / spotting

Im on spirolactone for my acne, itsbeen about 3 months. Its going great. No break outs unless i eat dairy.

However I'm noticing that im kind of spotting all the time. It's not a lot but enough for me to notice. She said the changes to my period are normal.

Anyone else been on this medication and notice it ? If so does it eventually calm down or is that how its going to be the whole time im on it?
