TTC and Sickness 😷🤒

Mercades • I`ll be 27 soon. 1 daughter. TTC #2. January is my month!!! 💜🙏🏽 A positive test for my Birthday! Yes!!! Please?!?
TTC and 4 days after ovulation I get sick. Doctors say viral infection and they said no treatment available. I'm feverish and have a swollen sore throat. Consuming a lot of cough drops and ibuprofen or Tylenol. I'm scared that if I am pregnant this time around that baby would end up weak in genetics... Is this possible? :( Any advice or help? I certainly didn't plan it... 😫🙏🏽
