I put head phones on my pregnant belly, is it too loud? Will baby be ok?

So I used my iPhone and put classical music on. I started putting headphones on my belly at 20-21 weeks I am now 22 week just today. I have probably put music on with headphones about 7-8 times for the baby; not completely sure could be less or more. I used these big headphones with the sponges on them for gaming or something so you could hear the sound in the headphones better... What I did not realize was I had the music on WAY too loud (as loud as my iPhone went). I could hear the music coming from the headphones when it was wrapped around my belly... I am so stupid =( I didn't come to think that it could be too loud for the baby.. I've felt baby kick and move around lots several times but did not realize it was probably startling my poor child and scaring it!!!!! I feel so GUILTY and it's stressing me out. I went to the doctor's today and I told him he said not to do that because the amniotic fluid amplifies sound! It freaked my bf and I out.. I forgot to ask if I could have effected the baby's hearing development.. all he said was to stop playing music and putting headphones on the belly. All of my blood tests and everything for any gestational defects ect came out negative.The heartbeat is at 150. Every test is very very good he says... so can anybody tell me if the baby will be ok? I am trying to stay calm and not stress out..
