Irregular light blood a week before period on T?+ some unrelated questions

Okay so I’ve never spotted before, I’m unsure what this is but I’m officially about 5weeks and 5 days on testosterone, moved up to .3ml SubQ. The first month I still had a period, I believe I was close to it anyways. But When I wiped yesterday and today I noticed blood but it was very light and inconsistent. I’m about 7-8 days away from my 2nd period on T and this hasn’t happened for me before. I’m suspecting it could be from the T? I’m honestly crossing my fingers that my period is either lightening or maybe not even coming this month. I’ve heard for some it stops this early. If anyone has any similar experience pls lmk..

I also noted once I switched to .3ml my bottom growth is accelerating which makes sense.. But my face is puffier imo and my stomach is too, I’m not gaining weight bc I still fit in the same pants and clothing. I also don’t overeat even if my appetite is increasing.

Is .3 ml (weekly) substantial? Especially for these changes? In 2 more shots I’m going to top off at my real dosage (.4), I know little about the average dosage.

When did you notice muscle changes? I renewed my gym stuff and I’m just hoping consistency will show more now that I’m at least a Month on T..

Overall I’m trying to compare my progress because I’m a somewhat paranoid person and to know others may have felt similarly to me and are moving on well in their transition would really help. I’m more euphoric than ever I just haven’t really had any community at all for this. Nobody I know has been through this or can relate.
