So long story short I had my son a little over a year ago and n ur sed him till 4 months when I suddenly became pregnant again and my milk dried up. And I mean dry like not even colostrum. Anyways I mc in september and we've been ttc for about four months. Af is supposed to arrive in six days according to good but I have a feeling I ovulated early. Right after my last period like a day after I got very fertile micas like eggwhites and it stuck for about a week even tho I was not supposed to o for another week. Well usually I dry up after o but (tmi) I've been consistently dry for about three weeks. I've been trying really hard not to read into symptoms so I don't become disappointed bit im so tired, irritable, and slight spike in appetite, and sore boobs. But then (tmi) me and my husband were fooling around three nights ago and he was sucking on my nipples and asked if I was lactating. I said no_ I've been completely dry for over six months even when stimulated. He said he got three god mouthfuls and I squeezed them and low and behold! It wasn't even colostrum, it was first milk! It's been consistently producing for the past three days, leaking in the shower and sometimes for no reason at all. I took a test and it showed up invalid so I plan on getting some more within a few days. Anyways, I was wondering if any of my prego mamas here have ever experienced this! Sorry for the long post!
