anyone have a tubal pregnancy?


Hello so am ttc. I started having really light spotting about 2 days ago (so light I don't even need a liner) Today my cramps increased but my blood didn't and normally they go hand in hand. I didn't think much of it until my mom mentioned it sounded like a tubal pregnancy getting ready to rupture. We didn't try this month so I havnt taken a test in over a month. If I was I would be between 6 and 7 weeks. My last period was different but still seemed like a period. I started a few days early and bleed pretty good for the first 3 days then went to barly spotting for 2. While it is different then my standard period I just assumed it was an off month. Anyway is this something I should be concerned about? I have not experienced a tubal pregnancy so I'm not sure what I should look out for... any advice would help.
