CD 12 what are my chances?

Hi ladies Baby Dust to you all firstly 💕

So I have one question for you all and it would be great to have some of you to respond

So ... cycle day 12 I had sex (yesterday) and I'm just wondering my chances of pregnancy? Glow says 27% but sometimes it's better to have some real idea and I believe that speaking woth other girls helps

My cycle usually is 28 days and this would be our first month of TTC so I'm unsure what I should be expecting to be looking for or anything like that

It would be great to have a friend on here to turn to and talk to about stuff like this as I have no female friends or role models to turn to

Thanks in advance guys

Good luck to you all xx
