Always works for my hubby. Let me ask you this tho...
In your first trimester can u tell me if u had the same symptoms?
-wet burps that taste nasty ( I dunno what its called)
-sensitive nipples that gradually get more super sensitive as the days go past
- gassy, slighly unusually tired
- urinating 1-3hrs... I would tell u more but I doubt u want to hear all that since these questions are the majority of the posts anyway, but I think its b/c everyone wants to know for themselves.
