Hello, well from the history you have given, you can confirm your pregnancy
by doing a urine pregnancy test after missing your period. ..that is from the day you expect your periods are supposed to start...Sometimes in early weeks of gesration , the urine pregnancy test may show faintly positive line or simply will not turn out be positive, this is because of low levels of beta HCG in early weeks....In case your periods are regular that is every 28 to 30 days, you can do test from 4 weeks, but if you have irregular periods
, or delayed periods, you may have to waite for another week....If you cannot waite for your result, then you may do a serum beta HCG
wherein the pregnancy can be confirmed earlier than the urine test....hope i was helpful to you. ..
