Your 9 months Pregnancy Week 4 pregnancy symptoms What symptoms can you expect for your 4th week of pregnancy? 1 of Ad break Your pregnant body This is the time you may have been waiting for, for several months: being able to do a pregnancy test. Many mums-to-be don't believe the first test, and do at least another one. So, to save money, you may want to think about buying a pack of two pregnancy tests, rather than two single ones. Pregnancy tests look for the presence of the pregnancy hormone HCG (human chorionic gonadotrophin) in your wee - which is why you have to wee on a stick. If you're pregnant, the level of HCG is high in the early weeks. You can generally take a pregnancy test from the day your period is due. If the test says you're not pregnant but you're sure, try and wait three days and then take another one. It may be that you conceived a few days later than you thought. Your breasts may be slightly tender or enlarged and your nipples may be more sensitive so look out for these as well. Now find out what you should be doing this week… What should you be doing this week? Firstly, make sure you read up about foods you need to avoid or be careful with now that you are pregnant.
