Patient: Hello, so i have had sex 3 times around my ovulation and then 3 days early i got my period, well this period was very light at first, then it got heavier but not as heavy as my regular period. And i have very regular periods. This period lasted 3 days. And today i am feeling very sick to my stomach like i am going to throw up. If i was pregnant i would be around 5 weeks. Could i be pregnant?
