Bahahaha Schmickers are you sure?

I was wondering about this also, I knew it happens to some people but was wondering if you can have no bleeding with the first pregnancy then regular "periods" with the next (if anything slightly heavier?)
I've had a few symptoms the last few months- increased CM, tired, headaches, feeling bloated, slight weight gain in the stomach region, morning sickness type nausea very occasionally, etc. I thought I was just being silly but DS is now off his milk and people keep suggesting it. I think it's probably just co-incidence though.
Also, probably a stupid question but would it show up on a HPT?

(sorry, not trying to hijack your thread just didn't see the point in posting my own on, essentially, the same thing.)
