Tips and tricks?

On day 5 of stim, and reading the threads. Had a few questions:

1. Stool softener: saw this in a few posts. When did you start/stop? So far no constipation.

2. I’m terrified of the trigger shot. Was it Lupron or hcg that is intramuscular? Any tips?

3. Thinking about buying the 30 gauge needles. Did you need a prescription in the US?
