Second period after miscarriage and SHARP pains

Sh

My first period after my miscarriage wasn’t like this. The cramps were normal. My next period isn’t supposed to start until next week, but these cramps are so strange. They’re sharp and they come and go. They’re only on one side and only in the front. And has been going on for three days now. If this all makes sense. Any idea what this could be? Again, these are NOT my normal cramps. 😫
