Fever during IVF FET - 2WW

Divsu • PCOS, annovulation! Two failed IUIs, IVF - 1st FET- miscarried @8 weeks. 2nd FET failed, 3rd FET chemical, 4th - BFP!!
Hi ladies, I’m currently 5dp5dt and in the 2ww of the FET cycle. I’m suffering with low grade fever(always between 98-99.5) 🤒and also a stuffy nose🤧. I called my clinic and they recommended taking Tylenol and Benadryl for my symptoms. Did anyone have similar experience and still got a BFP? I’m concerned that this might effect the implantation 😕
