I had protected sex on Sunday, June 18th (part of my fertile week) and when he pulled out, he said he felt sticky semen on the outside of the condom so he asked me to take plan b. According to <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a>, I ovulated yesterday and I had the cervixal mucus that usually goes along with that so I'm wondering if plan b just failed me or am I overthinking it?
