<s>[INST] Hello i have evening sickness and all the classic signs of pregnancy including a swollen stomach when i have never had weight gain starting from the lower regions i have negative pregnancy test and this has been happening two months could it be possible that even so i could be pregnant and how can i know for sure? [/INST] Hello dear, I understand your concern. In my opinion as the pregnancy test is negative there might be no chance of pregnancy. The symptoms of pregnancy are nausea, vomitings, increased urination, sore breasts etc. which start 2 weeks after missed period. So the bloating, weight gain might be due to some other problem as the pregnancy test is negative. Even the stress regarding the thought of pregnancy also makes one to feel the pregnancy symptoms. So relax and avoid stress. And consider repeating the test after a week. Usually the pregnancy test gives accurate results a week after missed period. Best regards... </s>
