I am a 21 year old female. I haven't pooped in about a week. I am having anxiety now because I am scared, yesterday I made myself poop even though I didn't feel like I needed to, but only little chunks came out pebble like. I was in there for about 30 minutes and only a little bit came out, like 3 pebble pieces. I drink a lot of water, eat a lot of vegetables like broccoli, a lot of spinach, bananas and apples. I also exercise everyday. I went to the clinic yesterday but they gave me miraLAX. I took it yesterday and today but I don't feel a change, I have only been passing gas. I haven't been feeling nauseous but have been having some cramps but I thought it could be because of pms since my period is almost here. When should I go to the hospital?.
