I am assuming that you are preggo and probably in your 3rd trimester? If not please excuse my response. Of course if you are nervous you should always call your dr just to be safe. I had heartburn SO bad with my DD!! They dr said that if it was really bad that they would have to run some tests, but he didn't thnk my case was too serious. He told me that I could take Pepcid Complete, the chewables. They really helped me! My friend took tums, I don't think that they worked as well. The good news is that everyone told me that my baby would have a full head of hair b/c of my heartburn, I guess it is an old wives tale, but it was true! My DD came out with a FULLLLL head of hair! :-)
Oh sweetie, this is so incredibly normal. lol. I had THE WORST heartburn when I was expecting. I swore dd was going to come out looking like Chubacca (sp?) You can take over the counter meds, but make sure to ask which ones, because some aren't safe. They are like savers and really help sleeping at night.
Some home remedies- spoonful of peanut butter followed by a glass of milk. works wonders for immediate help.
also, try not to eat right before bed or try to sleep slightly elevated.
