Ectopic?

So I have had a what seemed like a gas bubble on the left side of my lower abdomen pelvis area since Thursday. However; I just started my second month of birth control the Sunday prior. I have had no other symptoms of an ectopic pregnancy until this morning when I have pain in my collar bone. However all the pain is only painful when touched, otherwise it is unnoticed. I am worried because google.. also since it’s only painful to the touch but I keep finding myself touching and feeling my lower abdomen because I am worried. I don’t know what to think of it. I had sex with my boyfriend on 2/17 without a condom but I was on the combined hormone pill and he pulled out. Any ideas?
