maybe im overreacting

so this is my first and my appt got changed. im only 19 weeks and 3 days. i get some lower pain nothing bad except for when im curled over from tge morning sickness and i feel thise muscles tightening.. but then it goes away. but theres a lady at work that says i should see a dr because i havent felt the baby move mind you this is my first so im not expecting to feel movement yet but somedays i do get a pain followed by like a fluttering sensation then it stops.. but she kinda has me worried. idk i guess when did u feel ur first baby move. and is some pain ok like its the bareable pain because it always changes spot and lasts only a few seconds. another lady saif thats normal and as long as its not in the same spot then its nothing to worry about unless it lasts longer and hurts more. she said she didnt feel her first baby move til about 22-24 weeks. and i read sometimes u dont feel hr baby move til 25 weeks if iys ur first pregnancy.. just checking with u ladies and asking whatbu think.. maybe im overreacting maybe im not.
