Dealing with friends with fertility issues

So I was with a friend today and she had her daughter last June it took her and her SO over 4 years to get pregnant and have this baby. I am currently 26 weeks pregnant with my first, my husband and I got married in 2019.

Now while at her place we were having a friendly chat about pregnancy and the ups and downs. She then asked me so when did you and your husband start trying I told her in April. She looked at me stunned and was like you guys got pregnant your first month trying? I replied yes I bought a digital opk so We’d get the days right. After that she got kind of quite and cold very awkward. I know how much she struggled to get pregnant but was I supposed to lie to spare her feelings or just say I don’t remember or something? How do you all deal with your friends having the same issues? If you’ve had or are having fertility issues how would you have liked that question answered?
