My first month using metformin, femera and trigger shot

Ashley • I`m 28. TTC #1.
I'm new to infertility treatment. I was diagnosed with PCOS and started on fertility medication this month. I had my ultra sound this week and I had one mature follicle. So I gave myself the trigger shot yesterday. The metformin makes me so sick and the trigger shot also made me sick and I had a horrible headache ... is this normal???
