Paternity

Me and my husband had a threesome on vacation. I wasn’t suppose to ovulate for another week. It’s really hard for me to get pregnant. It’s me not him. Took two years to conceive our first and we have been having unprotected sex for 3 years this time around. My last period was on 9/23/20. I had a threesome on 10/04/20. My husband came inside me multiple times during our week long vacation. We got home on 10/06/20. I’m pretty sure We also had sex on 10/10/20. Found out I was pregnant on 10/30/20. The other person did not wear a condom but he did not ejaculate inside me. According to my app I wasn’t suppose to ovulate until 10/11/2020. My cycles are longer than usual. About 33 to 35 day cycles. When they measured the baby at 12 weeks it was measuring a few days ahead of my ovulation date which is why I’m scared there’s this possibility it’s not my husbands. I’m now currently 18 weeks and so full of stress. I took a noninvasive prenatal DNA test but twice already it has come back as insufficient fetus DNA in my blood stream. I’m so depressed and i feel so damn stupid. 😑
