For the past few days I have been experiencing a burning pain in my chest when I eat,some mild heartburn when laying down, as well as random sharp, stabbing pains in my breast and lower abdomen. I have been pregnant before, but I don't remember having these pains. My fiance and I do not use condoms (however, he pulls out), were not actively trying for a baby, but if I get pregnant, thats cool too. My last period was the last week of December. I have been taking Ibuprofen, maybe 4 a day, as my left side wisdom teeth are coming in. I don't think I'm pregnant necessarily, but the sudden onset of these symptoms has me curious as to what is going on. If anyone has any ideas, please let me know. It's not so severe that I'm ready to go to the Drs yet, just wondering what could be causing this.
