My wife had a miscarriage on 7th January 2019. DNC was done after 3 months of pregnancy. She got periods on 21 Feb and then 22 March. But she has not got periods this month till now. We checked with pregnancy test also. But it is negative. Only 1 dark line is seen. This month, She kept fast for straight 10 days. She used to have first tea of the day at 2-3 pm in afternoon and then light dinner at 9 pm. Nothing in between. Can this be a possible to reason ? Kindly suggest what all tests and treatment to be done. She is feeling pain in stomach but no periods not even spotting. Kindly help.
