I am married for 3 years now.. we had protected intercourse every time.. This month on oct 2nd we tried for first time and my husband ejaculated inside me..

So after first time release of sperm am having lower abdomen pain bloating frequent peeing and headaches..

Today morning am feeling nausea

Af is due 10/19

Is this all happening bcoz of first time ejaculation??

Or is my body preparing of pregnancy??
