Small amounts of spotting

MJ

Ok people are probably thinking I’m crazy based on my posts, I think I’m driving myself mental tbh

- BFP on Sunday and line has dramatically increased since then

- 2 days ago breast tenderness disappeared. I have been so worried ever since

- 3 days of cramp that feels a bit like AF but nothing appears - still slightly there on and off

- 4 hours ago, very small amount of spotting

AF was due 2 days ago. OPK detected surge 14 days ago so guessing I’m around 13 dpo?

Any advice ?? Or input
