Started retaking finasteride and minoxidil 2 weeks ago but I'm still shedding. Why am I still losing hair?

I stopped finasteride and minoxidil for three months in order to bank sperm. The results on the sperm were great (volume went up and the fragmentation went down) but the hair loss was imminent. I then restarted finasteride and minoxidil two weeks ago, but to my surprise, I'm still shedding hair--and lots of it! What can I do? Please help. I seriously don't want to go bald and want to regain what I lost. Should I switch medication or amp up the dosage? Please advise.
