That sucks not being able to be of work on Monday, but if DH is working too it would do your head in waiting for the clinic to call.
As for YOUR BFP on Monday, how far is his work from you. I think it would be great to turn up at his work and give him the news.
I have always wanted to purchase those baby Dunlop Volleys when I find out I'm PG as DH is a roofer and wears them every day and I too would surprise him at a job with the little shoes all wrapped up ..
