Threatened Miscarriage

Hi all, I am 5 weeks preg and this is my 4th. 2 days ago I experience mild bleeding like in pic, only appears when I wipe with tissue. Lasted only for a day. Never had this issue for the first 3 pregnancy. Had ultrasound done yesterday and baby was moving, but unable to hear heartbeat yet as doctor says it’s too early to use that feature for the machine. Doctor diagnose it as threatened miscarriage and issued progestogen pills. Anyone experience same issue and went on to give birth successfully?
