Haven't lifted in 2 months feels like chest is split apart

So I haven't lifted any heavy weights in a like two months. Before I stopped I could bench two 60 lb dumbells. Today I got an at home bench and tried to press two 50lb dumbbells. I did like a 3 sets of 4-5 reps. I was putting away my folding bench and as I was pushing it against the wall I could feel a pain on the attachment of my chest muscle to my sternum. I never felt like that before. I hope I didn't tear anything but could anyone give advice on what this is?

Also not sure what flair to add. I guess I just did too much but I only have a limited amount of dumbell weights at home :p
