Estrace & Bloating/ Cramping?

Hi-- I'm on 4mg (2 pills) of Estrace 3x/day in preparation for a FET.  This is my 6th day and I'm starting to feel seriously bloated and crampy-- almost like the beginning of OHSS which doesn't bring back fond memories!  Has anyone had a similar experience.  I see my RE on Thursday so I don't want to bother her now if it's normal but I'm feeling pretty cruddy.  

Thanks bunches!

I remember taking Estrace in preparation for a donor cycle though not as much as you're taking.  The bloating I experienced really came after the transfer.  It probably wouldn't hurt to call your re to ask since you're having so much pain - good luck & SSBD - jen
