I didn't start dramatically showing until about 30 weeks and now I am due here in about 5 weeks and I am still quite small and people barely can see that I am pregnant but the baby is perfectly fine. People's bodies are different.
Most ftm don't show till 6-7 months everybody is different
I showed at 14 weeks with my son and I'm 9 weeks now and showing already. My body type can't hide a baby. Some women barely ever get a belly. Everyone is different. All that matters is the baby is healthy.
