Am i being mother ?

I got opk bfp on my cd114 and today is my CD 19. Yesterday night while I'm sleeping I got severe pain in my stomach around navel area about a minute. Is this the pain of ovulation or pain of fertilised egg attached to my uteras ?

(I took 1000 mg of metformin and 50 mg of clomid on cd3-7)

Plz leave your opinion.

Thank you all.

Baby dust your way ..
