hi there you can get a test callled predictor they are about �3.99p from superdrugs they will tell you if your pregnant the same day your due on your period. they are also as accurate as the doctors tests. so give it a try. i was lucky i only had morning sickness once that coz i didnt eat breakfast. it might just be that your being sick because of the thought that your pregnant, i had a friend like that everytime she thought about a little baby growing inside of her she brought back everything she had eaten. i wish you luck let me know what happens with your test!!! x
