My wife had a miscarriage on 7th January 2019. DNC was performed. It was a 3 months pregnancy. Then she got periods on 21 Feb and then 22 March. She expected next cycle on 22-23 April. But, She did not have periods. We tested for pregnancy but it was negative on the kit. But yesterday, i.e. 2 May she got her periods. A delay of 10 days. Rather Painful periods than previous. Is it normal or do we need to visit a doctor ? Any test required ? Age: 28 Weight: 70 kg Thanks.
