Clit throbbing?? Help

So my clit keeps throbbing/pulsating I’m on my period it’s been like this since yesterday anyone know why? Also I’m 3 months postpartum this is m 3rd period since I’ve given birth. I haven’t had sex- single mom, also I’ve had the worst cramps during this period like sometimes the pain is 8/10... it’s annoying me that my clit keeps pulsating...
