6dpo!!!

So last night I was laying on my stomach and felt mild cramps and lower stomach doing some weird things… kind of hard to explain I got up because the puppy was crying… well my very light cramps turned into cramps not only in my lower abdomen but into my stomach near my ribs and into my back! Extremely uncomfortable I couldn’t fall back to sleep it wasn’t bad enough to take Advil but after a little while I decided to take some anyway! Spent the day with very light cramps but it started to get very intense again but went away pretty fast. Is that a normal implantation cramps type of thing?
