Hi ACB33,
I hope you're starting to feel a bit better. I would say that in my own case, I was suffering from signicant side-effects for the first 3 to 4 weeks that I was taking Fluoxetine. (However, as I was severely depressed and anxious at the time, it is extremely hard to tell what was caused by side-effects from the drug, and what was due to the depression or anxiety that I was experiencing already.)
I think the best advice is to go to see your GP to discuss any and all side-effects that any medication appears to be having, and to be guided by the GP's expertise. (If in doubt, go to the GP!)
(The GP should be well aware of the pros and cons, and various side-effects, of any medications that they prescribe. So the GP is the person to go to every time you have any fears, questions, or worries about any medication that you are taking.) The GP will discuss changing the medication; raising or lowering the dosage; or stopping taking the medication.
I have cut and pasted below a paragraph from the "GP Card" on the OCD Action Resources page, about medication and side-effects:
"Medication:
An SSRI such as fluoxetine, fluvoxamine, paroxetine, sertraline and citalopram may be given to adults either in combination with CBT (including ERP) or alone, depending on severity, and if the patient does not want to have CBT (including ERP), or it is not working. The patient will need to be closely monitored, particularly in initial stages for potential side effects such as akathisia and restlessness, increased anxiety and agitation, self-harm and suicidal thoughts. The medication may not take effect for up to 12 weeks. The patient must be informed about the possibility of withdrawal symptoms if the medication is suddenly stopped. A child or adolescent with OCD may also receive similar treatment with an SSRI, but a specialist will usually be involved."
I have also attached the links for the GP Card; and the Medication Information Pack; and the NICE Guidelines again:

So be sure to go back to the GP with absolutely any and all concerns you have about any medication that they prescribe for you. The GP may or may not know much about OCD, but they should have very good expertise about medications.
All the best.
