I am considering Prenatal DNA testing. They told me it is 99.99% accurate. My LMP was on June 1. I have a regular 28 day cycle. Had sex with #1 on days 13,15,17,19 and he ejaculated in me and I laid there for about 20 min each time/give or take. Guy #2 I only came in contact on day 17. Not sure if he had precum on him or not... but never ejaculated or entered me. Also, I am not sure if I was ovulating. Do I get this testing done? I am confused on what to do.
