For my first pregnancy I always felt abdominal pain as well. Been told it’s round ligament pain. You shld look out for signs of spotting/bleeding. Personally, I would go to gynae if I have any spotting/bleeding. And if the pain is bad and you are worried, It’s best to visit your gynae. Pls drink a lot of water and bed rest as advised by your gynae.
I had an achy feeling and lower abdomen pain whenever i walk too long. Best just bed rest and get as much of rest whenever u can. Your body is getting heavier with baby thats why.
I had achy feeling in my lower left abdomen before which I attributed to a growing tummy too!
