Hi everyone,I'm a newbie on here and looking for some advice,I had a miscarriage 4wks ago today,everything passed and the bleeding finished within a week on the 19th Aug was the first time we ttc again this was 9 days after my miscarriage,I haven't had a period since the mc,and yesterday I found out that i'm pregnant again how do I work out my due date I find it very confusing ,on Mon the 3rd I did a first response test it was negative and 4 days later with a cheaper test it was positive.
