Hello I am about 6 weeks or so pregnant with my second child. I also feel it at times but I have noticed that what helps me is drink pure coconut water or and water, keeping hydrated. It worked for when I had my period and it sure is working now.
I did this with my first baby and this baby as well it is your uterus growing to accommodate the baby. Unless they are strong cramps then u need to be seen. Moderate normal period cramps is a normal this from time to time.
I am 23 weeks and it didn't stop until 16 weeks or so. Maybe even a little later. I would get sharp pains, tightness, cramp like feelings etc. Very common as you body grows to accommodate baby :)
I am 6 weeks and 5 days and have the same. It's normal, it's our uterus stretching to make room for the baby to grow. I have mentioned it to friends who have added babies and they reassure me it's normal too!
