Hello Jasmine5
I know that Davina McCall uses a patch and tops up with gel. Her regime has been mentioned on this forum recently but I saw her video where she demonstrates her morning routine (she also takes Levothyroxine for an underactive Thyroid by the way).
When I saw her video I wondered if the progesterone in the patch was sufficient but her meno specialist is Louise Newson who presumably told her that it was okay. I expect Davina has regular scans as well.
So in answer to your question, yes some people top up their patch with gel but maybe only some meno specialists sanction it.
I hope this helps.
Take care.
K.
