Spotting during pregnancy memang scary, but the fact that your doctor checked and didn't see anything on the scan is actually reassuring, a lot of us have been there and it turned out fine, though some mums do bleed throughout pregnancy for various reasons. Since you mentioned the TVS scan showed more detail sebelum ini, maybe worth asking your doctor if another TVS would give clearer picture given your body type, just so you both feel more confident? Hang in there, definitely keep monitoring and report any heavy bleeding or cramping to your doctor straightaway, but try not to stress too much in the meantime, ya.
