Since several days back I have pain in my lower left abdomen and feeling nauseated along with stomach cramps at centre. I'm done with my ultrasound reports where a small microlith of 2.8mm was found in left kidney and a minimal clear fluid is seen in POD. First day of my last period was 31/10/2024 and I have done unprotected sex as well during mod of this month. But during intercourse these days I am feeling something fatty in my cervix.
