This is not an emergency, however, i would like advice because I ate a mcdonalds fry today and I think it went?

to my lungs, a little part of it, or I was imagining. I was holding my baby and multitasking and eating fries and feeding baby. A little part of the fry went in my wrong throat, and I was either imagining it slid down there or it really went there because i was coughing immediately. Then I was breathing fine, but a little panicky because I kept coughing but not vigourously. Then I read online in yahoo itself, yahoo answers, that when this happens, if you are choking you cannot breathe at all, and stuff does go down the wrong throat, or your lungs. I also read one guy had an m and m down his lungs and his body absorbed it. Then I read that some people said it went down the esophagus only, where you eat food, and stuff cannot go down your lungs without your body coughing it out. Then I read about pnumenia and how you can get some aspiration pnumonia. So I am wondering, what are the symptoms of aspiration numonia and how soon do they occur if you are choking? Because I am not getting any bubbly flem or pain in chest while breathing or trouble breathing, however, it is 1 and 1/2 hours later, and my coughing has gone down a great amount, by 70%, which is good news, and I am breathing better. The only symptom I am experiencing is an irritated throat, but it's not painful like a sore throat. it is just irritated, and sometimes when I am talking I suddenly break the word. But I feel like I am almost 100% recovered from this incident. When I first swallowed the fry and started coughing, the coughing was more intense. Now it is like five coughs in one entire hour. Plus, I am pregnant. I have enough sense to check into the emergency room, however, I do not believe I am choking. My main question is if a fry goes in my lungs, and a tiny portion of it, not the whole thing, then will my body keep coughing and not be able to breathe? Because i have been able to breathe just fine, just coughing a little. One other person thought they were choking and a lady said just gulp down water. Please tell me what you know and please remember, I have enough sense to know I am not choking, but I just want to know is there a fry in my lungs, what symptoms will tell me there is, or am I being ridiculous because people do not survive long with stuff in their lungs, no matter how big or small
