So my husband and I decided recently to start ttc. I got my birth control taken out (mirena) on the 29th of August. I started my period on the 31st, on time, and it lasted 3 days which is normal. On the 3rd we had sex. Yesterday and today I have been cramping and super nauseas. Nothing else is going on that I can figure out to be causing this. I know it's super early but nausea is how I knew I was pregnant with both our other kids also. I knew at about 2 weeks with both because of severe nausea. Could I already be having symptoms? Or am I over thinking this because we want another baby?
