Asked for female, 26 years old from Hyderabad
Today is 20 may and june will decide if you are pregnant after skipping the period. After 13 days of period, 7 th may, blood test for beta hcg may not be positive as this test is positive only after conception which is around day 14 th of the cycle
feeling heavy in stomach can be due to various reasons including infections in foodpipe or kidneys
get ultrasound done
get back here with reports for more guidance
I don't want to suggest deworming to help you because these medicines are toxic to fetus in case you get pregnant during the cycle. Do share with all of us after you skip the missed period.
