First time mom!


So I just found out last week I’m pregnant. According to my calculations I’m 4 weeks my last first day of my period was January 30th and the date of conception was February 7th. I have my first baby doctor March 20th. I’m nervous about it because I have endometriosis and I’m scared any small cramp could or anything could be a miscarriage I know it’s just me worrying. Any tips?
