Feel shy to reveal my bump

Hi all, new to this group. Am 35 yrs 4 months and 27weeks preg. I have a 5yrs old and I conceived after fighting secondary subfertility for 2yrs. After 2 failed ivf cycles I conceived naturally. Given the history this baby is literally a gods gift to me. Am extremely happy no doubt but I feel shy to reveal others that am pregnant at this age and choose clothes to cover my bump.

I know it's nothing to be covered and I should be proud but I feel uncomfortable as if am too old to be pregnant n first place. I dunno how to overcome this. Any inputs will be helpful.
