Light cramping - early pregnancy sign?

Hi! I am on my first month of ttc after loosing my baby at 24 weeks, 4 months ago. I also have a 2yo girl. Getting pregnant last two times was very easy so I am hoping we conceived on our first try again!

My ovulation was last Saturday and we did the bd in the previous week and the night before. Since a couple of days after the ovulation I am feeling light cramping, like menstrual ones but lighter and they are getting stronger. After is due in 8 days...could this be an early pregnancy sign? 🤞🤞
