Hallow Dear, Change in eating habits is known in pregnancy, though usually it is less eating with nausea in earlier weeks of pregnancy. Too much eating is going to bloat the abdomen causing breathing problems. In fact, missing a period is the first cardinal symptom of early pregnancy. The other symptoms appear about a week or two later. They are : 1. Nausea and vomiting with pica 2. Frequent urination 3. Breast symptoms: a. Engorgement and tenderness of breasts b. Darkening of nipples and areola with increase in areolar size. Montgomery s tubercles appear under the areola. c. Secretions from the nipples. If you are in doubt, please perform pregnancy test on the overnight morning first urine sample about a week after the missed period. Beta hCG test gives reliable result even few days before missed period. I hope this helps you. Dr. Nishikant Shrotri
