Plan b and birth control please help me gals! No reply’s on other posting

So I know this is careless but me and my husband had sex but he did not finish in me, we both no that for a fact! Because I got a sciatica pain and had to jump off 😭🤣 but I didn’t realize that according to this app I had actually ovulated 1 days before. So no longer ovulating but def still in my fertile window! Being at my old age I should know this stuff but somehow I do not! So I ran my butt to rite aid got a plan b and digital ovulation test kit. I know this might be off because I didn’t test previously. But on the day of intercourse I was negative ovulation and I’ve been testing since still negative. I popped the plan b pill and here we are a couple days later having sensitive breast and frequently peeing. Maybe all in my head

The day after this incident and plan b I did go to my dr and started my BC pill. So I guess I just need to no because I’m also a shy person and didn’t want to ask this provider that I had never seen with and with my anxiety 😥 but what are the chances? Husband is ready whenever I am but to be honest I’m not ready just yet! But if it happens gods timing is always right. Just turning to this group to see what my chances are as this was very unexpected and my hormones took off instead of my safety and condom wearing 😩
