Restarting Crina after a late start can cause nausea for a few days, but vomiting on everything plus two days of right-sided abdominal pain goes beyond a usual pill side effect. This combination needs a check to rule out gallbladder, appendix or ovarian causes, not just the tablet.
Next Steps
See a gynaecologist or general physician today for an abdominal exam and basic blood work or an ultrasound if needed. Mention the exact days you missed Crina, since that also affects whether it's still protecting you.
Health Tips
Go to emergency care now if the pain is sharp and one-sided, you can't keep any fluids down, or you develop fever.
