Symptoms of second acl tear?

Hi everyone,

I am 1 month and 1 week post acl op with patella graft and everything been going well. Today as I was getting in the car I accidentally put too much pressure on my surgical leg while getting in and since then ive been worrying non stop about if I tore my new graft. I didn't feel a pop or anything and no pain and I can't tell if the swelling is from already having surgery or if I injured it again..

Would I feel it if I re tore it and would I have symptoms?
