Help Please!

I’m not sure if this is even the place to post this but I need opinions. I’ve had three children and one miscarriage in December at 10 weeks. We have been trying to conceive. I’m 9 days after my period and I’m having stabbing sharp pains in my lower left abdomen. They are not constant they come and go and don’t last long. This has never happened to me before and I’m scared and worried. I’m just curious has this ever happened to anyone else before? What could be going on?
