Can you be pregnant even though you have been getting normal periods, but have a few signs of pregnancy?

'Signs of pregnancy' are mostly not meaningful. They are very similar to those of your menstrual cycle. Stress and fluctuations in hormones can do the same.
Some women do get a first period when pregnant, although mostly just spotting. A very few women have had more than one period when pregnant.
In short - there is NO way to know if you are pregnant except for a test.

Do you understand what your period is? Each cycle the uterine wall gets expanded to accept a fertilized egg. If no fertilized egg attaches, the wall is flushed and rebuilds for the next ovulation cycle. So if you are getting your normal flow you aren't pregnant.

There are many symptoms of pregnancy that could mean something else. You should see your OB/Gyn if they persist

A women may have some light spotting the first month or two, which is often confused by some women as a period. But the only way to know if you are pregnant is a pregnancy test
