Question: hello doc , i am 52 days since last period ( LMP- feb 22,2014) . i had a long cycle once and after that my cycles were pretty much in the range of 32-36 days . But again i am back to long cycles .i did have unprotected intercourse around march 22-24 , noticed a little light blood red bleeding mixed with the discharge from vagina on 25 and 26 march, attributed to ovulation bleeding . now i am confused if it was ovulation bleeding or anything else .. i do not have any pregnancy symptoms or maybe i dont know how they may feel as i m a bit on the lighter side . for my satisfaction , did a HPT yesterday and got a negative . i did the test only because i felt extra tired when climbing stairs . i was almost on the point of fainting and feeling dizzy , could'nt go any further had to sit down for 5 mins to take breath .. pls note that i had just eaten and was climbing the gangway of a ship ( thought the dizziness mite be due to climbing immediately after eating heavily) . i do get tired everytime i get on the gangway but this was so alarming hence i had to test . kindly advise on the steps i can take to determine if i m pregnant or is it just my body thanks

Thanks for the clarification doc . Could u pls elaborate on UPT and USG and why it is required
