Body currently fighting off and infection. can this mess with my periods? i have had a sinus infection for two months. no longer ovulating and spotting and bleeding in between periods. finally on some antibiotics. 2 normal paps and normal ultrasound?

"Sinus infections" are not generally associated with menstrual irregularities. Stress from any source can delay ovulation, which in turn delays onset of menses. If pregnancy is possible, obtain a serum HCG test to be certain. See your GYN physician for guidance, as low dose oral bcp's stop ovarian hormones, and will correct the irregularities described.
