I have been on birth control for nine years now and last month I was on antibiotic. I was suppose to start my cycle Tuesday instead Thursday through Saturday I had a brownish-red dishcharge. This has never happened to me and I have never missed my cycle except for nine years ago with my first child. I have taken a pregnancy test and it was negative, but I have been dizzy at times and feeling like my sugar drops everday. I have also been waking up to use the bathroom and I usually dont do that. I had to take something to have a bowel movement because it had been almost three weeks. Should start a new birth control pack tomorrow or wait?
Hi, Thanks for the query through Chat Doctor virtual clinic.  I understand your concern.  The illness & the antibiotics you had taken cause weakness. Dizziness, weakness. Constipation is other post illness symptoms, which can cause delayed periods.& abnormal menstrual pattern.  Home pregnancy test of urine is best done after 8 days delay in periods. If you have done it earlier, please repeat it. -ve pregnancy test at proper time rules out pregnancy.  - If you are using oral contraceptive at a stretch for 9 years, you can take a gap for a couple of months & use alternative method of contraception in the break.  - In case you had a break within 3 years, you can start with new pack of contraceptives on scheduled time... You have to test for pregnancy in case next period is also problematic.& check for pregnancy & go for MTP (as oral pills are notorious for causing fetal malformations).  Thanks.
