Need advice

Lissa • My name is Kellissa . I am 21 yrs. old & happily married 😊 I am expecting baby #2 ❤️❤️

I’m 14 weeks tomorrow. The past 4-5 days my lower abdomen has been very sensitive . Sometimes I get pain and I can’t lay down or sit down using my stomach muscle because it hurts and wanted to know if it’s something normal to experience with a First time pregnancy or if I should go to the ER to be seen ??? PLEASE HELP
