Weird menstrual change

My menstrual period changed this year in the beginning from January to March. My menstrual last 5 days. So it start In January first week for 5 days then it started again at the end of the month and ends three or two days of the next month. Its been doing that until beginning of March. Me and my husband are trying to conceive. But haven’t had my period and it’s already 32 days it hasn’t come back. Plus I’m having this weird sharp pain that it takes only few seconds. What should I do or should I be worry?

Just check pregnancy test & check with doctor if its positive

Have you checked with your dr?

Maybe take a pregnancy test? Or see a doctor

Take a test, I was cramping up like I was due on & didn’t I was actually pregnant
