7 weeks and weird feeling/symptoms

I’m 7 weeks currently and my doctor recently put me on iron pills. They don’t make me constipated like she said but I have noticed that sometimes (not everyday) I feel the urge to poop or poop multiple times a day throughout the day. I get cramps that sometimes I’m assuming just Aide in that feeling. Is this normal? Like I know their suppose to change some things up but I was expecting to be constipated and I seem to be having the opposite affect. Maybe it’s just me and maybe I’m just being ridiculous but I was just wondering if anyone else has experienced this. 🤷🏻‍♀️🤷🏻‍♀️
