Just looking for some thoughts.

Just a couple weeks ago I found out I’m expecting baby #3!🥰 yesterday I had my first prenatal appointment. As I was talking with my midwife about when my last period was she said I could be more time pregnant than I think. I had a period July 24th that lasted 4 days but then on August 9th I started spotting which I thought was my period. The bleeding lasted 3 days the blood flow was a little more than just spotting in those 3 days but it wasn’t super heavy either. I am either 8 weeks pregnant since July or I’m 5 weeks pregnant since August. I haven’t had an ultrasound yet and I will be getting one soon I just want to hear other stories. The wait to find out how long I really am feels forever.😅😂 My question is have any moms or soon to be moms experienced a little more bleeding than spotting and where more time than expected? I know implantation bleeding is a thing I just never experienced before in my past pregnancies. Thank you for taking the time of reading my post!☺️
