Educate me!! Could I be pregnant ¿¿

Husband and I had sex days before the app says I should be ovulating, he did not pull out🙄😷. I know that's very irresponsible and now we're sitting here looking dumb waiting and hoping my period actually starts. I know I still need to wait a couple days BUT hes been worried it was too risky HE GOT ME SAVING OUR BABY'S STUFF!!!😭💀

We did the dead on the 16th and started ovulating on the 21st.

It could be all in my head but I've been so freaken tired like I haven't felt like this since my 1yo was a newborn. Also I missed a meal today and I swear inwas about to pass out I've never felt like that only when I was pregnant.... smh that's the one that actually got me thinking I could be😑
