IUD ISSUES/ Possible Pregnancy

I have been on IUD for 5.5 months and my period skipped this October!

But in October I did have two days of SPOTTING (light light pink) nothing else. Then I’ve been getting

• LIGHTHEADED these past two weeks,

•BLOATED

•extreme CRAMPS the past 3 weeks,

•NECK PAIN 2 days in October

•WHITE VAGINAL DISCHARGE

((((TOOK A pregnancy test LAST WEEK- was NEGATIVE)

My cramps are only on the right side and uterus, nothing happening on the left ovaries.

GAVE BIRTH SIX KONTHS AGO, is my period supposed to stop this soon?

I’ve been having unprotected sex with my husband all these months and we never use the pull out method.
