Ttc & in need of comfort

I literally had unprotected sex 2 days before ovulation & the day before & somehow I still managed to get my period this month!!! I also just continued having unprotected sex for the rest of the month 3-4 times a week!! BEYOND PERPLEXED HOW I STILL GOT MY PERIOD THIS MONTH AND THERES GIRLS UNEXPECTEDLY HAVING BABIES THEY DONE EVEN WANT AND IM OVER HERE TRYING 😭 just a huge sigh of disappointed for me and my boyfriend everytime.
