You can be worried but not paranoid. Symptoms for pregnant mummies will come and go. However, sometimes can be prolong. But this is not for everyone. It depends on each individual hormonal changes throughout the pregnancy. Unless you feel that there's not baby movement, baby hiccup, excessive bleeding,excessive pain then you should be very very worried. Every scanning or meeting up with doctor, I would suggest to ask questions if you are in doubt or curious esp if you are first time. Be positive and trust your motherly instinct and ensure you look after yourself very well. Take care & all the best ❤
