Heya,
I was on estrogen pills for a bout a year before my doc switched me to weekly injections. I take my injections subcutaneously. When I first began injections, toward the end of the week I'd begin feeling blue and would even begin craving my next injection, but after just a couple months I started feeling much better. My injection dosages remained the same. Maybe I "equalized" or something, I am not sure. Personally, I wouldn't want bi-weekly as it would probably leave me feeling bad toward the end of week two just before my next injection.
Here is a topic where I talked about it
https://www.susans.org/forums/index.php/topic,232545.msg2070717.html#msg2070717It's all better now. However, sometimes I still do get a bit of a phantom period as you describe. It is indeed more intense on injections. Could be a placebo deal though, so please keep that in mind.
From what I have read the estrogen shortages are a thing, but I am just sure to call in my refill as soon as I am able just in case anything gets backed up. This was a recommendation from my doctor! I was never unable to get my estrogen in a timely manner. For reference, I am in the United States.
My testosterone put up a fight against oral estrogen so my doc opted for injections+finasteride. This brought all my numbers within a female range. With that I do feel better and I am beginning to see changes after being on injections since December, 2017. It's like the physical aspects (how I look) of my transition really picked up steam after beginning injections. The changes experienced are as follows, and remember I was on pills for about a year before beginning injections:
-More boob growth. Before I was working with little more than buds, but growth has now accelerated to the point I cannot just walk around in public with a thin t-shirt and no bra.
-Softer'' looking face. Subtle though it may be, within that framework it's still a marked difference and I suspect things are going to get even better.
-Slowed hair growth. I was never particularly hairy to begin with, but now it's really slowed down. For example, I can make it two weeks without shaving my legs whereas before I only got a week out of a shave.
-Emotions are much more intense. I'll cry more and now I am far more likely to be repulsed by conflict of any sort.
Switching to injections was one of the best things for me. It's almost like when my HRT really began. I hope my words here today have helped you in whatever you decide.
I wish you happiness, safety, and love as you continue your transition.
