Oh mrs w I'm so sorry if this is AF
how many cycles is it since your mc? What have the previous ones been like? What were your cycles like before? If I were you I'd go to the drs to get the ball rolling in case you need extra help, hopefully the AC and vit b will sort it out first though. Drs often don't do anything til you've seem them a few times for the same thing x the chances are your body is just taking a bit longer to sort itself out and it'll all be fine but I really understand how gutted you must be
Your picture of your dd's childhood is beautiful though, I think we should all be aiming for that! I've totally given up potty training now, she can do it herself when she's ready! My dd does things in her own time in her own way. She was climbing stairs before she rolled, we tried desperately to teach her to crawl but she bottom shuffled! She took ages eating regularly, didn't sleep through til after 1 and she just stopped asking for feeds, and she gave up Breastfeeding in her own time when she was 2.
