If you're getting periods than it's unlikely that you're pregnant. Some women do however had bleeding throughout their pregnancy, so it is possible that that's what's going on.

Try another pregnancy test, use first morning urine, or see your doctor for a blood test.

Agree, if these are regular periods, then your cycle is just getting changed, or having off months, that does happen to many women.

But at this point a pregnancy test should show, the first one sounded too early
