First, I will tell you that I have had 9 miscarriages. (Yes, a lot) and one double (twins) ectopic pregnancy. So I've gone through it a few times. There is a chance. It all depends on your body chemistry. BUT most of the time, it would take more than 2 weeks for your hormones and ovaries to get back into sync. If you have a good doctor, you should be able to call them and tell then that something doesn't feel right and you would like to get a follow up hormone level test. The way you're feeling might not be caused by another pregnancy, but still by the last one. The fluctuating hormone levels could make your emotions go from happy, sad, nervous, anxious, scared, depressed, etc. It's hard. You should call your doctor and ask for an exam and a blood test.
