Short lp after miscarriage

🍐Heather • Mmc in May 2015, mc in January 2016. BFP 2.7.16! Rainbow baby 10.20.2016🌈🎀 TTC #2 with new diagnosis of Multiple Sclerosis
Everything about the timing of my cycle after miscarriage is regular except a long period (9days) and short luteal phase (9-10 days). Still ovulating according to temps. Can anyone share similar experiences? I feel discouraged.
