late period..

I've came to the conclusion that life sucks all around when you actually finally want something. Yes I want a baby! So I spotted on and off for 4 days 27-30 Then through the 31-2 I got my period. I was suppose to have my monthly on the 16th of January. I've never missed or had any compilations like this with my cycle. but anyways so I googled missed periods implantation bleeding. The whole 9 yards of it.. I got so many different answers. I'm at the point that I may need to get checked out just to see what's going on. I'd appreciate it for some feed back if anyone has had this happen to them before. Thanks! 😊
