I knew I was pregnant

I had been TTC for 3 months. Then on December 24th I ovulated. Although ovulation was painful we BD’d. I immediately felt like this was it! Then on December 31st I was awakened by the feeling I was coming on my period. It lasted for about a minute or two and went away. Then about 3 minutes later I felt it again lasting for a minute and then it never happened again. I laid there from 4am till 7am so happy because I knew it was implantation. January 3rd I tested and got my BFP. It’s just so crazy how I felt like this was it immediately after sex and it was.
