I've had an experience and I'm thinking it's not normal. I had the monthly right before starting T (the placebo week of the pill). Of course I stopped taking birth control pills because I would be starting T soon. I had another monthly the week I first started T. I was started on a really low dose and it's been gradually increased.
I've read how some guys are on T for months & months before their monthly stopped, but that was my last one. During the time it should have happened again I was still on a lower dose but nothing. Haven't had one since.
As for blood tests I had to have a blood panel done before starting T. The endo believes I've reached the T dosage I should keep taking and don't increase it anymore. Six weeks from reaching the target dosage I go to get another blood test done (a little over 3 months into T).
I find it concerning your doctor hasn't done any blood tests. They're not just to check your T levels. The doctor also monitors other hormone levels, liver function, blood sugar levels, cholesterol, etc. I believe most doctors like you to get blood tests every 3 months the first year. I think after that the norm is every 6 months. But each doctor is different and there are other variables like health issues and such. Not knowing your T levels or what T is doing to your body is dangerous. Plus, if your T levels are too high it turns to E. I find it neglectful and dangerous that your doctor doesn't have you get any blood work done. Has he worked with other transpeople before?
