Hi, Elle, maybe you don't need to do the costly prenatal test. Do you have the exact dates of the split, the sex and when your first ultrasound was? Write them out like this if you do:
first day of last period ___
date of separation from husband ___
date of sex with Mr. Wrong ___
(protected? unprotected?)
date of reconciliation with husband ___
when did you find out you were pregnant? ___
date of earliest ultrasound ____
due date given to you at that ultrasound ___
Are your cycles super regular (like, they always come like clockwork every 28 days) or do they vary?
