I'm having a hard time tracking my periods. The last period i had was 35 days apart from the one before that. Glow calculated my period to be in 30 days but would come on the 31the day like just a 30 day interval. I was scheduled for urine mcs and a swab test today but I couldn't do them cuz my period came unexpected on CD 28 instead of a day after CD 30. How am I going to keep track of my period and ovulation date? What am i to do? I'm in paid cuz of the infection. I have intense back pain, sharp pains in my ass and lower abdomen I'm worried it might be a PID. I did a pelvic exam but the doc had an impression of vaginitis. I'm to take some drugs but I can't until I take the test(after my period). Also I did a pelvic scan like three weeks ago and everything came back normal. They didn't mention my fallopian tubes and I'm worried about them. What can I do? I appreciate any advice. No harsh words I'm begging you. My next doc appointment is on the 27the of this month
