TTC After a Baby

Amanda ⭐️
Hi!
So my LO is 6 months old and I would like another so they are close together. I'm exclusively breastfeeding but starting solids slowly. I haven't gotten my period back yet. We BD on the 19th and 25th. Two days ago I started spotting. (Pinkish. Maybe a little red?) but def not bleeding like a period. Lasted a little over two days off and on. Does that sound like implantation? It would follow either of those dates time frame.  I never had bleeding with my first.
