Hello, I would be happy to help you with your question.
While it is entirely possible that you too have twins, you would not be "showing" at just 5-6 weeks pregnancy
. In all likelihood, the uterus
could not be felt above the pubic bone with twins until after 12 weeks.
What you might be noticing is a hernia
which is a small defect in the abdominal wall. It often appears as a bulge on one side or the other. You should bring this to the attention of you doctor when you go in for an ultrasound
at which time you will also see if you too are having twins!!
I hope this helps and good luck!
