On July I had two periods but it was in synch with my normal cycle duration. If yours were close though I'd oh to your Gyno...
Sorry i dont want to scare u or make u worry that isnt my intention cause i know how stressful pregnancy could be but if u experienced this then go take a blood test and inform your concern to your doctor, they will suggest u do the same. Good luck i hope everything works out for you:)
I had two periods in one month seemed like a regular period with cramps and i knew that something was up but ignored it then one week after the second period i was rushed to the e.r cause i fainted and it turned out that i was 5 weeks pregnant but it was a tubal pregnancy (ectopic). I loss that pregnancy and was told that the bleeding i experienced wasnt my period and it was bleeding from the ectopic. From what i have heard is that bleeding twice could simply be implatation bleeding and it could be a normal healthy pregnancy but most of the time it could mean something....so u.should get checked.
