I got my iud about 3 months ago and I’ve had very long periods the last 2, one lasted 17 the other 14 days. My period hasn’t been exactly on time according to <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a>, my last period started the 17 (21 days ago) so I’m 4 days late. Should I worry I’m pregnant? Or could <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> just be a little confused with my odd periods? I don’t use any other protection besides my iud, thank you!!
