Implantation Question

I’m just curious to see if any of you did experienced implantation, how did it feel?

I’m having some weird twitching like sensation on my left side of uterus. Not cramp like it painful at all. It’s just a weird feeling.

And was wondering if it’s normal or if it could be implantation or anything else ?

My period is due in 5 days, so idk if it’s too late to implant. I tracked ovulation with OPKs and my peak was on the 17th so ..

Thanks for the insight ladies 🤓🥰
