Nexplanon and ovulation?

Shannon

Hi all. I just got off nexplanon about a 2 weeks ago. How long does it take before I ovulate again? My <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period app</a> says I was supposed to ovulate on Tuesday but I took an ovulation test and I didn’t come up. However, I’ve been super nauseous the past couple days and my stomach (where period cramps would be) is tender and not like I have to urinate. Could I already be pregnant and that’s why it’s not coming up on an ovulation test? Advice and experiences please!
