Hi!
If you were my patient, the first thing I would do is a pregnancy test.  A tubal pregnancy is one of many possibilities.  I would want to know about this one ASAP though.
If your test is negative, you have a bit more time to work with. I do think that an appointment with your doctor would be a good idea.  There are so many things that can cause irregular bleeding, and so many different options for treatment.
Hope this helps!
Good luck!
