Gonal-F with Clomid?

This is my first cycle assisted with meds and first I took Gonal F(62.5 for five days--CD1 to CD5). I went for an ultrasound today(CD8) and we saw three follicles in the right and three or four on the left. However, none were bigger than 1mm. They told me that they will check my levels via bloodwork and chances are, I'll end up starting 100mg Clomid once a day for five days starting today(CD8 to CD12). I have heard of Clomid and Gonal being used together, but I've only seen the clomid used first then the gonal not the other way around. Anyone have the same or a similar situation?
