Blood blister

So we were away from the house yesterday and I was using my single electric pump the suction was strong, even though I had it on the lowest setting. Last night when I was fixing to do my last pumping session I noticed the blood blister on my nipple. Do I let it pop on it’s own or do I pop it? When I was finished pumping this morning I noticed that there was a little drop of blood that mixed with the milk (but didn’t make it to the bottle). Any advice would be appreciated. ☺️
