7 weeks tomorrow...

Went to bed last night with some mild back pain... took some Tylenol and woke up in the night with some cramping for like 15 minutes— it hurt pretty bad— but I can’t ever tell if it’s gas or cramps... anyway, I was really freaked out. Once I calmed down the cramping subsided and I feel a lot better this morning. Very gassy, but no cramps or back pain. I have no bleeding or spotting, and my boobs are still sore this morning. Should I be freaking out that it’s ectopic or a miscarriage or something? Has anyone been through this?
