Day 11 of my 1st period since I had Kam via c-section! Doesn't hurt but I do feel a bit exhausted but then again I'' the stay at home mom of an 11 year old going through Cheerleading try outs and a almost 3 month old going through a growth spurt with a Husband that got switched to mid day shift! (3:30-midnight) I took my 1st Depo on Jan.26th and they told me my monthly will be irregular but I'm not sure if this is ok....🤔🤔🤔 Anyone have the same experience?
