<s>[INST] i have been undergoing fertility treatments, and I am now in the two week wait. I had an Ovridrel shot on the 15th, and starting on the 23rd, I have been running a very low grade fever (99.1 to 99.8) continuously. Could this be because of the Ovridrelm, or could this be an early sign of pregnancy? [/INST] Hi,Thanks for  writing  to HCM .Low grade fever is not a common side effect of ovidrel injection. Common side effects are abdominal discomfort, pain, nausea,vomiting , breast pain.low grade fever is not a early sign of pregnancy too. Early symptoms  of pregnancy include fatigue, vomiting, nausea, increased urination, breast enlargement or pain.Dont loose hope you can be pregnant without these  symptoms. I would suggest you to consult your doctor for your fever as it could be because of other diseases . Hope I have been helpful .Regards Dr.Deepika Patil </s>
