Ok ladies we have been ttc past few months we lost our last child at 25 weeks a year and a half ago so I feel like the time has been right we have a 8 year old and a 5 year old I've been trying to track but I've never been a on time period person at the beginning of April I had a full period coming off depo at the end of January spotted last month and then I had some brown spotting Friday for a bit then some this morning! My glow calendar says I'm supposed to start the 21 st any ideas ladies??!!!!
