Cramping on femara

I am 7dpo today and have been feeling cramps every day since 1dpo. On 3dpo I had a sharp pain on right side. And yesterday 6dpo and I had another sharp pain in my left side. Did anyone else have this and it ended with a bfp or is this maybe cysts? For the record - I do have mild PCOS and Doc says mild because I don’t have cysts just all the other lovey symptoms but I wonder if the Femara has created them? For the other days in between it never hurt. Could just feel them.
