Csec needs to cut through so many layers of muscles & fats to reach for the baby, so I suppose a sudden brake won’t hurt the baby. Moreover, baby is protected in amniotic fluid. However, I can understand how u feel. Will worry and get anxious. For a piece of mind, you can go to doc and have a check .
I got the same experience as you. Took an sbs bus from plaza sing area and the bus drove off very fast. Even before i could grab anyting. I also accidentally hit against the pole.. hope u r ok! I just realised i didnt tink much about it. Now i hope i m ok!! 😂
If anything happens you can see signs with in 24 hours. whenever your baby hits his head . Apply an ice pack right away on the bump to ease any swelling
Maybe you can call your clinic for their advise!
