Anyone experience Implantation bleeding on one pregnancy but not the next?

[winolady]

Just that really.. I didn't with DC1 but think I might be second time round, I had spotting this morning and nothing since.. normally my periods are heavy and once started boy I know it!

Yes, nothing first time round but did second time! Light spotting

I did first time (thought my period had arrived and had a massive gin - two days later when it was still just those few spots I tested and was positive).

Nothing second time.

Yes - first time I did. 2nd I didn’t (ended with a mmc) 3rd and 4th I didn’t. 5th I did - significant bleed at period time.

First time no, second time yes, third and fourth time no. Implantation pain with all of them though.
