Miscarriage/ Chem preg # 2 about to start clomid and trigger shots. How bad are the trigger shots?

Kristina
So my husband and I have been TTC for 3 years now. We are currently experiencing our 2ond Chem pregnancy/Misscarriage? We will be doing Clomid which I am familiar with unfortunately. This will be our fifth round in the last two years.  We will be doing a day US and a day 12 US to check and see if we have a healthy folical and then we will do the  HCG trigger shot. Ok I am not afraid of shots just never had one in my stomach before. On a scale of 1-10 how bad are they? LOL
