Do you notice it all the time or just when sitting or standing. Im almost 22 weeks and noticed if i sat more i felt more pressure but if i stood up a few minutes the baby would shift.
No I notice it when I'm standing. I kinda wanna say when I'm laying down too.
Its probably just where the baby is positioning him/herself and ligaments stretching. As long as no bleeding you should be fine. I would mention it to your doc at the next appt but if it gets painful too much then call and see what they say.
