TMI but have questions!

Ok so when I was pregnant with my daughter, I don't remember having to use the bathroom this often! (Going Number 2) I'm roughly 4-5 weeks along with my second and I have to go at least 5 times a day. Maybe more!! Is that normal? I'm also having mild back pain and cramping. It's been going on for about a month. I remember with my first I had cramping and thought it was my period (then I took a test and found out I was pregnant) but I don't remember feeling like this with her for this long. I'm also extremely bloated and i have a lot of gas lol Just curious and would like some advice! Thanks in advance!
