I lost my previous pregnancy due to no heartbeat as well at about 24 weeks after suspecting no movement for 1-2 days. Went to kkh for a scan and found no heart beat. got induced on the same day. After a post mortem test, they found blood clot in the umbilical cord which likely is the cause.
Now I’m on blood thinner (asprin and clexane) daily to support my current pregnancy.
If you decided to induce labour, suggest to take all possible test (blood test and post mortem) to find out the possible reason although they may tel you sometimes there is no reason before you go for the test.
