I enjoy just looking for patterns in my life, have googled Angel numbers as well. Funnily, I check the time at exactly 13:37 very often (nerds will know). Also 14:41 and similar times. And throughout my pregnancy, I've had magpies appear in groups of 3, we shall see if the nursery rhyme rings true :)
Congrats girlie! Google 1 angel number meaning and so on, the more it repeats itself, the stronger the meaning. On the top of my head 444 is protection, 333 support, 222 something to do with partnership = 2 = a pair, 1 = new beginnings and I think 111 positivity. I think a lot of the time they're just what you make of it, for me 444 = my higher power and so I tend to see the number when I feel the most in need of universal support or down xxx
