What’s wrong with me?🙄

For months I’ve had late periods but my periods are either spotting are very light. I’ve taken pregnancy test and got 2 faint positives and 5 negatives. I have some pregnancy symptoms that come and go. My stomach started growing the past month or so. I’ve NEVER been fat and i usually have a flat belly or a tiny pudge but this is noticeable and round... opinions or suggestions?
