TTC after MMC 2 weeks ago and aspirin

Natasha
Hello! So on the 5th October I found out at 10 weeks my baby stopped growing at 8 weeks 5 days. I had a d&c the next day as I had no bleeding or cramping. 
I went to my OB yesterday and she did an internal and everything looks normal and my lining is nice and thin. She said she noticed my lining was very thick when she removed the baby. She then told me to take Cartia (aspirin) one daily from now until I am 12 weeks pregnant. 
I guess my question is - did this work for anyone? And what now? Hubby and I just DTD lots coz I still have hcg in my system and kinda just don't know where I'm at! 
Thanks
