I am 39 and had a tubal 10 years ago. I have never missed a period and now I am almost 2 weeks late. I am having all the symptoms and my belly is huge.did a home test and it was negative

Unlikely that you're pregnant, especially since you had a tubal. But it's not impossible.

The best time to test is when your period is 2 weeks late. You stated that you're almost 2 weeks late. So you tested too soon. Wait until you're 2 weeks late, then test using first morning urine. If that test is negative, wait and see what happens with your next period. You could just be having an off month.

Your belly is not huge and can not be huge at 2 week late, there is no change or sign or pregnancy as the belly large at 2 week late, So a huge belly has to be another issue other than pregnancy, unless you are two or three MONTHS late, not weeks.

You can not (or should not) start testing till you are at least 2 week late, then try testing every week if negative.

If your belly is really huge and has just started this in last couple week, I would see a doctor, since it has to be something else
