Could it still be likely?

Patient: I’m kind of confused. I haven’t had sex in two months. Lately my abdomen has been swollen and my breasts have been tender. I didn’t skip any periods, though I believe it’s possible one may have been lighter than usual. I took five tests, two different types, all negative. Though the blue dye ones had a faint, faint line the width of a hair in the positive direction. I just feel very off and I was wondering what the odds are that I may still be pregnant even though I didn’t seem to miss my cycle and tests are still coming out negative this late.
