Could I be pregnant?

Grace

Ok so my boobs never get tender or sore even when I’m on my period and they have been for about a week or two. And I started my period but it’s been more like spotting a little bit and then bleeding a little bit and then spotting then bleeding but only a little. And I usually bleed pretty heavily. Also I usually only have cramps for the first 2-3 days and I’m on day 5-6 and still back and forth between spotting and bleeding and still cramping. Also my boobs are definitely getting bigger so that’s another reason I been thinking I might be and also I have been getting sick and having diarrhea often. And test are coming back negative but Idk if I might need to do a blood test or if it’s too soon or what.
