Praying.

I'm 7dpo ... First round of ttc baby #2. I had my Paragaurd removed on 7/26 after almost 4 years. We had sex 4 times during my fertile week , especially on the "optimal day"... I don't feel any different except moody... I had a little cramping today but nothing alarming. This is my second cycle without my iud so I'm still getting used to life without it. I'm praying this happens , as I'm a teacher and i would have a May baby. since we do not have maternity leave. I'm scared, excited and nervous. I'm tempted to test on Monday since I'll be 4 days before my monthly friend is due. Should I or just wait ?
