Dear sir/ma'am, after my marriage, my period is very much irregular i.e. From 35 days to 60 days. I was pregnant in may 2020 but after 3 months my doctor suggests that heartbeat not seen in ultrasound so abortion was done in july 2020 by d&c. After that again my period was irregular and now I am detected pregnant on 03.11.2021 when tvs ultrasound done it shows that there is 4 week sac in cavity but fetal node is not present. My doctor says that it is due to irregular period and gives medication for one month and called for further follow up. Medication involves dydraboon 10 mg, ecosprin 75, dufol and cough hp 5k (weekly). Kindly guide me that fetal will be normal ,i am very much worried because it has passed 46 days from my previous period when tvs was done.
