I want to know whether during pregnancy periods occur?

I want to conceive but got my periods now but its very less as compared to my regular periods. Also I'm having vomiting sensation too.

Please help

You will not have a period. Very light bleeding or spotting may happen the first month. Have you taken a pregnancy test? Using first urine of the morning

The first symptom of pregnancy is a missed period. If your period was lighter than normal, then wait about 2 weeks and use a HPT.
