Red raspberry leaf tea question

Katie • Stay at home mommy as of 6/30/16!!!
And I able to still drink the red raspberry leaf tea that I was drinking before I got pregnant? I was drinking it after going through our UI my first time and being on Clomid and noticing that clomid thinned  my lining out. But obviously the lining does grow 1 to 2 mm the day and whatever Tia I was drinking before hand must have done my body good if I'm pregnant now.  
I'm 4 week and 6 days. is it  mOK to drink the tea or should I hold off????
