Expert answer:
When "the baby goes down" can be a sign of pregnancy (especially when associated with other symptoms and a context of possibility of pregnancy), but does not mean that every time "the baby goes down" the woman is pregnant, quite the contrary, in the most of the time does not mean pregnancy. Since you have already menstruated the chances of pregnancy are small, but if you are still in doubt you only have to take the pregnancy test, give preference to the blood test, it is more reliable.
