Hello! i missed my period its been 34days since my last period. typically, practically always, i have a metallic, bloody odor in my vagina before my period. ive had the smell now for 1 week. is this assurance ill get my period? or can i be pregnant

No guarantees ! : 20 year old women typically have regular periods, meaning every 28-35 days. and the absence of one for 364 days is quite unusual. The odor you describe sounds like spotting or a small bleeding leakage. A pregnancy test and or a trip to the OB-Gyn will resolve the question about pregnancy issues. Suggest you see your OB-Gyne, polycystic ovary disease may present this way...

Pregnancy test: If you has sex since your last period and missed your period by 4-5 days, do a home pregnancy test. If the result is negative repeat the test 4-5 days later unless you get a period by then. Use first morning urine and follow the instructions for the test carefully. If you do not wish to be pregnant, use contraception all the time, every time. You may consider implanted contraceptive, or IUD.
