Cramps

So my fiance and I are trying to have our second child. I just got my iud out on July 28th and got my normal 5 day period on the 12th. Yesterday (Friday) was my ovulation day and we had sex the night before. All day Friday I had pressure like cramps and today I've had just dull, consistent cramps and random times of feeling weak like low blood sugar. I can't remember if this is how it was with my first pregnancy so I'm wondering if this is normal after ovulation? Or is something wrong with me? Or what? 😅
