I want to be there for my son but idk how

Plx plz plz keep unsupportive transphobic comments off my post. I will report them. My son is transgender and just turned 18. I've made a few posts. He had randomly gotten a period at his friends sleepover. None of his friends knew he was trans and this was his first period in a while. His friends mom helped him and her son (his friend) brought him chocolate and played xbox with him nd didn't even bring it up. His other friends had questions but seemed to accept him. He went back to rhat friends house for another sleepover and a different boy there fingered my son in his sleep and he woke up to it. His friend(the one who accepted him from the beginning)beat the shit out of the guy there. That boy who molested him was arrested. My son seems to be doing better. I have a feeling him and that friend are dating(son is pan, his friend is bi). We had a situation a few months ago where we weren't able to get his hormones and ge freaked out but it's all been sorted put. He was off them for almost a month. I think maybe starting them again has been effecting his mood. But he texted me at work ssaying he had something to tell me. I said ok. I get home and he's asleep. So I go to bed and wakeup to him screaming. I go in his room and hes screaming no and there's blood all over his bed. I said "It's fine. We will talk to

your doctor about it". I was thinking it was another period but it seemed like wau too much blood to be a period. He was crying and ran to the bathroom. He was in there for 3 hours and I just heard him cry and flush. I changed his sheets and wrnt to talk but he doesnt want to. I asked what he had to tell me but he said its not important anymore. I want toto support him but im not sure how.

@Lindsey I've never had a miscarriage before so I wouldn't really know 100% what it looks like. What would be a good way to support something like that?
