I was just wondering, how long after ovulation before you get implantation cramps? I used a ovulation kit last week and my surge was detected Friday so I had sex, I also had sex on Sunday. Today I have some pretty bad cramps but I know that you can get cramps when you release your egg. Do you think the pain is from releasing my egg and if so, should I have sex again tonight? Or do you think it could be implantation cramps? I would imagine it would be to soon for implantation but I need some advice. Thanks in advance for your help.
