It’s normal that you might not have the symptoms anymore as you are getting closer to trimester 2 now. Symptoms can be on and off. Also, you do not want to have these symptoms because it will make you feel horrible. Some people do not have pregnancy symptoms throughout their pregnancy, while some people will have. Having symptoms doesn’t mean you are pregnant. You can be pregnant without symptoms too (luckier mommies). As long as you do not have bleeding, massive cramp/pain or weird discharge, baby should be safe.
Diff preg diff people feel differently. If you are worried contact your gynae for a scan to ease your mind. Take care.
Make an appointment with your gynae for a peace of mind.
