Pre cum pregnancy or Plan B?…

S🌺

My hubby & I started off sex without a condom & when we finished he had the condom on. The first day of my last period was 5/29 and on the app it says I’m “low fertility” but online I checked on an <a href="https://play.google.com/store/apps/details?id=com.glow.android">ovulation calculator</a> and says my fertile window is 6/12-17 and today 6/16 I’m “approximate ovulation”…is it common to have a pre cum pregnancy? I can take a Plan B but I’m not sure if it’s even worth it.

Any advice is great and rude comments are not needed. Thank you 🤗
