Oral hcg sucks. There is no point in using it. I doubt you took 20ml of nolva a day. Probably mean 20mg. You were supposed to take an Aromatase inhibitor (AI) on cycle and use nolva for post cycle therapy (pct).
You should also have your post cycle therapy (pct) ready before you start your cycle.
If you still have nolva, wait two weeks after last shot and use it for four weeks at 40,40,20,20. You could also get clomid or toremifene to run with it.
