Im 5 weeks pregnant with my seond child, i was having really bad cramps but no bleeding the other day and i went to the ER, they said everything looking and seemes fine and normal. I woke up in the middle of the night last night with excruciating pain in the left side of my back and i tossed and turned until i couldnt lay there anymore and had to get up. Just curious if this is normal bc i didn't have these pains with my first child.
