2 missed periods 2 non at home urine test negative. Can i still be pregnant?

[Joce2412]

I'm 18 years old and I've had my period for 10 years. My period is usually regular its only delayed a couple days nothing more. Its been 2 months that I haven't got my period. The last time was Oct.2 its now Dec.8 I'm worried because a month ago I got diagnosed with chlamydia and took the medication. My Doctor did a pregnancy test and it was negative so she said it was fine if I took the medication. A went back a couple days later for HIV blood test she then took another pregnancy test which once again was negative. A week after that my doctor called me telling I had an abnormal pap result. Can the chlamydia infection and abnormal result affect my period or am I actually pregnant. I have another doctors appt. Dec.16 , what should I do? Am I pregnant? Is it a side affect? Should I take a blood pregnancy test? Please help I'm devastated it's too much to handle at once. Please give me some feed back.

hi
im not sure if medicine for chlamydia could affect ur periods in any way but if u r concerned then speak to ur dr when u go, he may want to do a blood test to c if u r pregnant.
