Last cycle I took clomid 25 mg and also had to take trigger shot. 8 days after trigger shot the hcg was out of my system. This month I took femara, had an hsg test done and also took trigger shot. It has been 11.5 days since trigger shot and couldn't stand it so I took a test. Within one minute I got a BFP. Should the trigger shot be out of my system if it were gone by day 8 last month? I'm having lots of cramping and extreme fatigue.
