Symptoms are unreliable, as PMS, stress, etc can all mimic the same symptoms of pregnancy. The only way to know if you are pregnant or not is by a pregnancy test. It is possible to get a false negative test, so you can make a doctors appointment to find out what is going on. Because you are young, it may just be that your hormones have not stabilized yet, so you will have different timed periods. Though because of the heavy clots, I'd make a doctor's appointment. If you took a test before the "weird" period you had, it would have come up positive if your were pregnant.
i have been having a brownish discharge for the past 2 days and i was supposed to start my period the 6th of this month and havent started yet.the last time i had sex was sunday of last weekend.
last month i think i had a miscarige but i took a pregnancy test a few days after i had sex and it was neg.but i had alot of signs of pregnancy my boobs were sore and ferm i could feel the glans swelling up and i was a few weeks late for my period then i started to bleed like 4 weeks after my missed period it lasted about and hour or 2 then stopped then it started up again a couple days later it was mostly blood clots it lasted for a week and the pregnancy signs i had they were going away except the glans in my boobs their still there but not really ferm and hard like they were before or sore.and now i just took a test a few days ago and it was neg.could i have been pregnant and miscarried could i be possibly pregnant again???????????
