Mirena IUD & period

Kestrel • Mommy of 2. Wife. EMT.
Hey ladies! I've had the IUD before over a year ago but took it out to get pregnant. Now it's my second time and got it inserted 6 weeks post partum (back in July) I had a long light period in October and nothing since. I've been very moody a bloated for about 2 weeks now but still no bleeding. Is it normal to have period symptoms with no bleeding for the IUD?
