TRYING TO GET PREGNANT💥

Hi ladies sorry, but just wanted to ask a question I have had these really weird symptom, lately witch isn’t like me, ( I know it could be down to anything)

But everything I eat, I feel like I’m gonna puke, I got a period. This month but it only lasted 3 days. Then it was brown discharge for 2/3days. Can anyone give me advise should I take a test or?x thanks.
