Lumps in thigh

Hi i noticed a lump st the back of my leg while pregnant just above my knee but brushed it off and then life got in the way now 17 months on its not grown or shrunk,  its hard and doesn't move but aches when being touched too much I have also since found 2 more deep in my thigh, you can't see then just feel then the ones in my thigh you have to really press down to feel. Im going to the doctors when im back from holiday in 3 weeks , im just seeing if anyone else had this, everywhere I look it says if its lipoma it should be soft but these are solid.
