Getting pregnant after testicular cancer

An

My husband and I got married December 2018 while on our honeymoon he notice a lump in his testicle. As soon as we got back we went to the Dr. where they told us it was testicular cancer he has one testicle removed on February one month later I found out I was pregnant (conceived mid January). On may he had his 3 month check up where they discovered it had spread to his abdomen area where he got surgery to remove his 2 tumors. The dr. then told us he would be needing chemotherapy which he had 4 cycles over the course of 3 months. Never did they mention about him loosing fertility (maybe because they saw I was pregnant) but now we been trying for 2 months and nothing I am just scared we won’t be able to have anymore children. Has anyone gotten pregnant after TC chemotherapy on your own? If so how long after
