cranky, moody & cramping after 3 day transfer

Well today is my blood work day... I'm 7 days past retrieval and 3 days after transfer and I'm feeling so cranky, moody and my cramps are horrible. Last night I felt the worst pain near my left ovary. I've been so withdrawn and ignoring my gf i feel bad because it isn't her but these meds have me all messed up. Has anyone felt like this during these days after transfer? I'm so nervous.. we test for our BFP on dec 23rd (fingers crossed)
