I’ve had my Skyla IUD for about two years now and I never got a period until 8 months ago then I go get very light period every month (I got my IUD checked at the gyno when I got my first period and it was in place)

This month, about two day “late,” it’s never super accurate but this was according to the app) a few hours after sex I had a little blood. Shortly after I had a 36 hour along allergy attack and no more bleeding.

Could the allergies and lack of period relate? I was having awful anxiety during the allergies as well. Strings seem to be fine.

Any thoughts would help!
