I started solids in June and I think that's why it came back. DS is
7.5 months and sleeping thru night and eating solids 3x day.

most likely your cycle hasn't got back to normal so it's not a missed
period, just a longer cycle than usual, after my first I got cycles back
fairly early 4.5mths, but they were all over the show in terms of timing for
another 6 months or so.
