So I'm not sure what to think of things I'm pretty sure I'm not pregnant but I also am not sure what to think so I'm wondering who else postpartum has had this complication....ive had my first normal period 2 weeks ago I'm 8 weeks pp this weekend. I got my depo shot while on my period and the hubs and I decided to give sex a first try 4 days later after period ended and we've been fine ever since. So it's been two weeks since my normal period and now I'm spotting again for the past 4 days and menstrual cramps. Last time I had the depo for 6 years I never had a period or spotting after it and now I am so I'm not sure if it's related to the depo or if this is just normal postpartum stuff I just think it's odd because I didn't have this issue last time. Anyone else had spotting 2 weeks after a normal period?
