Yes to Nancy's post.
The zinger doesn't have anything in it that would or should make you feel funny. If it does, it's probably just between you and the tea. I wouldn't worry unless you felt a tightening in your uterus, in which case, obviously, stop right away. But that doesn't sound like what you're describing.
Raspberry leaf tea does NOT start labor. It helps make uterine contractions more effective and strong, possibly because it has a lot of calcium and other good stuff in it. You can drink RLT at any time during pregnancy. Vitamin C, on the other hand, can cause contractions if you take too much.
It's not that the stay-at-home-parent gets to stay home with the kids. The kids get to stay home with a parent. Lucky Mom to DD1 (4 y) and DD2 (18 mo), Wife to Mercenary Dad
