Talk to Gynecologist on Pain During Intercourse

Aslamualaikum I got married in December 2019. And since last 3 months we are trying to convince but whenever we tried for intercourse I feel sharp pain in my vegina sometimes it continues after intercourse. I did complete urine RE and beta HcG test everything is normal but still I feel pain . I want to know the reason . Is there something serious about which I should be worried ???? My menstrual cycle was normal till March but from March I sometimes got my periods 1 week early. I felt slight spotting on 29th of may and I got my periods on 12th June which lasted for almost 2 and half days.
