ttc after miscarriage

How long did you conceive after your miscarriage (I had a d&c done so please include if you had that or it was natural)? I found out at my 12 week appointment, baby stopped growing at 8. I had the d&c two days later. Friday will be a week since the d&c. It took us 14 months and one <a href="https://glowing.com/glow-fertility-program">IUI</a> with femara to conceive that baby (our first). I'm having a really rough time and praying I'll be able to conceive fast once I'm cleared. Should I immediately start fertility treatments again or try on my own? Any experience or advice is very much appreciated! Thank you!!
