Understanding Possible Pregnancy Symptoms & Negative Tests

Question
Hello;
i was wondering if you could help me. I think I might be in my second trimester. Family and friends have seen and felt the baby moving. I have gained appr. 23lbs in the last 4 months. I  have taken two home preg tests and they were neg. I have been to the doctor he also did urine test it was neg. He has ordered a blood test and ultra sound. He says i am showing all the signs of being preg. but can;t feel my uteris. What is wrong. My last period was on Sept.4 to 7. it was lighter and shorter then usal. so were my 2 previous mp. I am regular on a 23 day cycle. Do you know what could be wrong.

Answer
If your last period started on September 4, and you have not had any bleeding since then, a pregnancy test at this time would be accurate. If you have any doubts, take two blood tests for pregnancy (Beta HCG) 48 hours apart. If there is a doubling of the results in 48 hours, it indicates a viable pregnancy. If there is a halving of the results in 48 hours, it indicates a miscarriage. If both values are less than 5, you were never pregnant. A sonogram will also let your know what is going on. A woman cannot feel any fetal movement until after she has been pregnant for 5 months or more, when the uterus is above the level of the belly button. A sonogram will tell the size of your uterus and would see a fetus if there is one. Good luck.
