Pregnancy week 2
Please see week 1. Due to the more general developments in the first two weeks of pregnancy, the information about the first and second week has been combined in order to keep the information in cohesive units.
If you feel the site could benefit from having a separate article on the second week of pregnancy, please feel free to contact us with your recommendations.
Current guidance (today's medical sources): Because development in the first two weeks is general, the original guide combined weeks one and two. Ovulation around the end of this period releases an egg that may be fertilised, usually in the fallopian tube, marking conception. A continued folic-acid supplement of about 400 micrograms a day and avoiding alcohol and smoking remain the standard general advice during this time.
Contact your healthcare provider promptly about heavy vaginal bleeding, severe or persistent abdominal pain, a high fever, severe or sudden headache, vision changes, or fainting. Seek urgent care if you are worried — these can be signs that need medical attention.
