Aw mama, I totally understand the worry, spotting in early pregnancy is really scary, pero the good news is your doctor already found baby's heartbeat! Please keep your follow-up appointments with your OB kasi sila lang ang makakasabi ng tama kung normal lang ang spotting mo or kailangan ng extra care. A few of us mums have had brown discharge early on and it turned out fine, pero kailangan talaga ng proper monitoring, hindi lang home doppler. Keep taking your Duphaston as prescribed at try to rest, I know it's hard not to worry, pero you're doing great! Samahan mo lang ang doctor mo sa journey na ito, okay?
