Taking progesterone & oestrogen after 12 weeks pregnant advice please 😊

Hi ladies, I’m hoping someone might be able to help me or share what you did (if relevant). I had a frozen embryo transfer & have successfully conceived 😊. I was taking progesterone & oestrogen (Lubion injections & Cyclogest pessaries) prior to transfer & advised to keep taking if pregnant (I’m pretty sis they said until 12 weeks). I am now 12 weeks & 5 days. I have 5 Lubion injections & 7 Cyclogest pessaries left from my prescription. I called the nurses at our IVF clinic today to ask if I should stop taking them or keep going until the prescription runs out. The nurse advised that it’s up to me?? She said they advise up to 12 weeks & I can either stop all together now, keep going until they are finished or wean off them… not the most helpful response & I’m not sure what to do now. Does anyone have any experience of this or any thoughts/knowledge on what’s best to do for me & baby? I appreciate you can’t give medical advice, but I welcome any thoughts 😊. Thank you all! Allison x
