Side effects are common and temporary. Here’s how to cope with each one and when to seek help.
Common Side Effects and Relief Strategies
Bloating and Abdominal Discomfort
Why it happens:
- Ovaries enlarging (up to size of oranges or grapefruits)
- Multiple follicles developing
- Fluid retention
- Hormonal changes
What helps:
- Hydration is key: Drink 8-10 glasses water daily, more if very bloated
- Protein: Eat protein-rich meals (helps fluid balance)
- Small frequent meals: Instead of large meals
- Avoid salty foods: Worsens fluid retention
- Loose comfortable clothing: Don’t compress abdomen
- Heating pad: Gentle warmth can help
- Rest: Lying down relieves pressure
- Gentle walking: Light activity, don’t overdo
Duration:
- Increases throughout stimulation
- Peaks around retrieval
- Improves few days after
- If pregnant, may continue 1-2 weeks
Normal bloating:
- Uncomfortable but tolerable
- Gradual increase
- Able to eat and drink
- Able to urinate normally
Hot Flashes
Why it happens:
- Estrogen fluctuations
- GnRH agonists especially
- Clomid commonly causes them
- Body thinks it’s menopausal temporarily
What helps:
- Dress in layers: Easy to remove
- Cool environment: Lower thermostat, use fan
- Cold drinks: Keep water bottle handy
- Avoid triggers: Spicy foods, caffeine, alcohol, hot beverages
- Breathe slowly: During episode
- Cool shower: Before bed
- Light bedding: Cotton sheets, fewer blankets
Duration:
- While on medication
- Resolve when medication stopped
- Temporary menopause symptoms
Expect them – extremely common, not dangerous.
Mood Swings and Irritability
Why it happens:
- Hormonal roller coaster
- Estrogen and progesterone fluctuations
- Stress of treatment
- Sleep disruption
- Worry and anxiety
What helps:
- Acknowledge it: “I’m hormonal and that’s okay”
- Warn loved ones: “I may be moody, please be patient”
- Self-compassion: Don’t beat yourself up
- Time out: Step away when overwhelmed
- Exercise: Releases mood-boosting endorphins (gentle only during stims)
- Sunlight: Natural mood lifter
- Connect: Talk to others going through it
- Counseling: If severe
What doesn’t help:
- Trying to “control” emotions
- Feeling guilty about mood
- Isolating yourself
Tell partner: “I may cry over weird things, snap at you, or be all over the place emotionally. It’s the hormones, not you. Please be patient with me.”
Duration:
- Throughout treatment
- May continue if pregnant (pregnancy hormones)
- Improves when meds stopped
This is temporary. You’re not losing your mind.
Headaches
Why it happens:

Very common and harmless.
Fatigue and Low Energy

Duration:
- Throughout treatment

Annoying but harmless.
Serious Side Effects: Ovarian Hyperstimulation Syndrome (OHSS)
What Is OHSS?
Over-response to fertility medications:
- Too many follicles stimulated
- Ovaries very enlarged
- Fluid leaks from blood vessels into abdomen/chest
- Can be mild, moderate, or severe
Risk factors:
- PCOS
- Young age
- Low body weight
- High number of follicles
- Previous OHSS
- Becoming pregnant (hCG maintains it)
Prevention:
- Lower medication doses if high risk
- Close monitoring
- “Coasting” (pausing meds if estrogen too high)
- Triggering with GnRH agonist instead of hCG (IVF only)
- Canceling cycle if too many follicles
- Freeze all embryos (avoid fresh transfer)
Mild OHSS (Common)
Symptoms:
- Abdominal bloating and discomfort
- Mild nausea
- Diarrhea
- Ovaries enlarged
Management:
- Drink lots of fluids
- High protein diet
- Rest
- Monitor at home
- Usually resolves in 7-10 days
Affects 10-20% of IVF cycles – usually manageable at home.
Moderate to Severe OHSS (Rare)
Symptoms – Call Doctor Immediately:
- Severe abdominal pain and bloating
- Rapid weight gain (more than 2 pounds per day)
- Nausea and vomiting (can’t keep fluids down)
- Decreased urination (dark, concentrated urine)
- Shortness of breath
- Tight or enlarged abdomen
- Dizziness or lightheadedness
Can be serious:
- Requires medical monitoring
- May need hospitalization
- IV fluids
- Drainage of fluid (rarely)
- Blood clot risk
Emergency Contact: 026965055
Peaks 3-7 days after hCG trigger (egg retrieval).
Worse if you get pregnant (hCG keeps ovaries stimulated).
Prevention is key – clinic monitoring prevents most severe cases.
When OHSS Resolves
If not pregnant:
- Improves with menstruation
- Ovaries return to normal
- Usually within 1-2 weeks
If pregnant:
- May worsen initially
- Lasts longer (weeks)
- Requires monitoring
- Eventually resolves
Severe OHSS is rare (1-2% of cycles) with modern protocols.
