I am not sure why the pills were stopped while you were on antibiotics.I recently had a bout of influenza and then a mild infection for which I was taking pills and then antibiotic was going on.However, there's nothing to worry.If you have used pills for even 2-3 months before this incidence, the chances of you conceiving is very small in the first 2 months of stopping the pills.In some cases, pregnancy has happened even after 12 months of leaving the pills.You may want to do a quick urine pregnancy test in case your periods are delayed by more than 7 days.

Hi I ve been on the nur isterate for almost. 5years. I have skipped about 2 shots last year but finally decided 2 completly stop this year. My last shot was in Jan 2016. I have been on anti biotic called Metronidozol 400mg for a period of 5 days late in March 2016. Will it have any effect on the contreceptive?

Hello, I have been on the birth control pill for 3 years now but this past month I had a UTI and surgery done on my ear so I had been on anti-biotics two week prior to having unprotected sex exactly a week ago. The next morning I went and bought the morning after pill. My period is regular and I was supposed to start it today. I have not started it and while standing in the shower 30 minutes ago I began to black out and my head was hurting it, I felt so heavy and just fell and I was still concious because I was calling for help but I saw nothing but static. I couldn t really see anything. I really hope this is just a side effect and not pregnancy.

Hi, I ve had the contraceptive implant since January, and I ve never really had any noticeable side affects, but three weeks ago I got put on anti biotics by the dentist and was warned that they may affect my contraception, so I used protection. But these last two weeks I have been experiencing quite a few unusual symptoms, which could either be side affects to my implant(which would be strange seens as I ve had none since I ve had it in) or symptoms of pregnancy. My boobs have been extremely tender and achy, I have been craving strange foods that I would never usually like, and some foods that I usually love are knocking me sick, I have been going to the toilet an awful lot, 7-15 times a day, I ve had serious mood swings and I m very tired a lot of the time. I plan to visit the doctors on Monday but I m very scared that, if I have happened to fall pregnant while on the implant, would it affect the baby in the future if I decided to keep it? Research says it is unlikely, but many women online said the implant caused them to have miscarriages after three months, a little reassurance would be great right now thank you!!!

Hi Dr. Dilip Raja,

I am a 23 year old, sexually active male. I have had a history of fungal infections (jock itch, infected toes, etc) all over my body. About 3 months ago I started having severe pain on the tip of my penis that worsened after urination, ejaculation and chaffing. I was tested for all STDs at 2 months and 4 months after possible exposure and everything came up negative. I was put on 2 months worth of antibiotics which did nothing to improve my condition. Recently the pain at the tip has gone away but there is now a small line (indentation) along the base of the head of the penis which is the source of the discomfort. It is greatly affecting my sex life. I hope you can help.

hello i have pain after urination, weak urine stream and trouble releasing all urine from bladder. also feel some stillin tubes. slight pain during ejaculation. burning worse at night but starting to be more frequent threw day. had this about 3 weeks with bad burning so i went in after 3 weeks of trying to drink lots of water bc i thought it was a urinary track infection since my wife gets them alot. after 3 weeks wheni took pee test i was tested postitive for clamitia, but my wife who i had unprotected sex with the whole 3 weeks with symtoms came out negative for everythiig and got full paps and swab done, when i returned for 2nd test after meds i could alrdy feel it comeing back, but test came up negative for all stds. whats wrong? its becomeing more difficult to pass urine, more frequent burning the burning is like it pulsates from groin area when it does burn not a steady burn. it can hurt more when flexing that area or moving postions in bed. 26 years old 6 foot 140p ptsd and depression from iraq

I had unprotected oral sex with a girl I met at a party 5 days ago. She performed fellatio on me. The very next day I had a slight burning sensation at the tip of my penis. This got much worse the next day and so I sought out a doctor who suggested it was likely a fungal infection of the urethra caused by an infection in the girls mouth. I am booked to have an STD check after two weeks have elapsed just to check if it s something like chlamydia or gonorrhea. The burning sensation is nearly gone after two days of anti fungal medication and I have had no burning while peeling or discharge and my urine is clear. Does the diagnosis sound correct to you? Thanks
