Implantation pains

[Luna92x]

Hello everyone,
So on Saturday night through to Sunday I had severe cramping which felt like period pains. They were bothering me slightly but not too much but then I went to sleep and around 4am they woke me because they were very much present. Sorry for TMI i had to sit on the toilet as it felt like a stomach ache/cramps but I didn’t need to go and the only way i can describe the cramps were those of period ones but more intense.
On saturday i would of been due my period in 5 days time (this Thursday) ive never had pains like this before I am 29 years old do you think this could be implantation?

I don't think impantation can cause any pain, as it's on such a small level. I read somewhere that at that stage the embryio is smaller than a mosquito.
If I had to guess I'd say it's because of progesterone. Those levels are both increased during early pregnancy and during the end of the cycle before AF arrives. So, unfortunately it can be both.
But in the end, who knows. Weirder things have happened!
