Spotting after sex

Shana

I'm 38, 6weeks 1day pregnant with my 🌈 baby and it's a rollercoaster of emotions. few days ago I went to the ER for spotting after sex the ultrasound only showed small gestational sac @ 5weeks 7days. still spotting today I had a follow up US confirmed IUP and there was the yolk sac 😊 seem like the pregnancy is developing.so I thought. a hour or so after getting home I passed 1 medium sized clot 😞 no cramps and still only spotting I'm so worried has anyone ever passed clots had a successful pregnancy?
