unusual bleeding

[morellalynn]

i got my period the first weekend of this month as normal. it lasted 3 days normal as usual it was very light though. the odd thing is the next weekend i started bleeding again not enough to bleed out (if that makes sense). that lasted about 3 days also and today (weekend also) i start bleeding again (again not enough to bleed out). i am very concerned. i am not on birth control not pregnant. i am only 34. i have been on penicillin for a couple weeks up to and including when i started my period though.
