Uy mama, I totally understand your worry, lalo na with your history. Please message your OB agad or call the clinic, okay? Better safe than sorry, especially since you're on duphaston.
The good news is your baby's heartbeat was perfect just days ago and walang bleeding, which is very reassuring. But symptoms can shift during early pregnancy, and only your doctor can tell you if it's normal for your situation or if the duphaston is affecting how you feel. A few of us mums have noticed pregnancy symptoms come and go, pero you really need your OB to check and give you peace of mind. Sending you hugs, you've got this.
