Please help! Scared!! Ectopic?

Please help - I’m really freaking out!

2 days ago at 13 dpo I got a faint bfp. Yesterday at 14 dpo it didn’t get much darker and towards the evening got lighter. This morning I can barely see a line.

I would chalk it up to a chemical pregnancy (I’m now 15 dpo and on day 2 of missed period with no sign of it...),

BUT for the past 3 days I’ve had this pinching cramping feeling on my right side where the ovary/tube is. It gets worse after I eat and better when I lie down. Feels better when I press it. Does this mean ectopic or more likely chemical?

I thought that if the tests get lighter it’s chemical and with ectopic they are still there just don’t get dark as fast? I guess it could be a “good” sign that the lines are disappearing? That maybe it’s not ectopic?

I’m terrified because I’m away from home in another country for weeks now and I don’t know when I’ll have access to medical care!
