Irregular cycle after miscarriage?

Britney • Angel Mama to National 💙

I miscarried at 6 weeks in December. I had a period 4 weeks after and it was about a 25 day cycle which is normal for me so I figured things were back to normal. This last cycle was only 20 days which is really short for me. I’m trying to get pregnant again and do an <a href="https://glowing.com/glow-fertility-program">IUI</a> but that’s kind of hard with irregular cycles. Is this normal 3 months after an early miscarriage?
