Implantation spotting

Larissa

Me and my bf had unprotected sex on march 10th and we didn't use pullout method like we have been, and it's now 2 weeks later, 3 days after ovulation and I had light pink cervical mucus when I wiped. I'm wondering if I could be pregnant, me, my bf and my daughter all have a cold and it's been about 2 weeks as well so it's been hard to tell if any of my sick symptoms are related to pregnancy.
