Please help!! ⚠ warning kind of long

Shante • Hi my name is shante brown and fiancée name is tyreese we have been trying for baby #2 for about 3 months now. It`s been a rough road but hopefully soon we`ll get our bfp! 😊😊
Ok so I just had a baby 10/10/16 I was breastfeeding baby boy but due to technical difficulties I stopped around 11/02/16 I then got my period 11/28-12/04 everything was normal and that's when it said I was suppose to come on. Ok...so here's where I'm confused I was suppose to get af 12/26 but never did I am now 17 days overdue and am on CD 47 I googled some reasons and webMD said it could be due to breastfeeding but again I stopped first week of November and got a normal period after that. I have not took a test because I live in a rural town and I have no car. And its just been to cold to take the kiddos out. Me and the father have had a couple slip ups and I'm terrified I could be pregnant again so soon. I scheduled a doc appointment for 01/17/17 so I'll find out then but I'm trying to find out if any other ladies in here been through the same thing. Anybody with similar stories or advice please feel free to comment I could really use it. Thanx😊
