Hi,
Thanks for the query.
As you used condom the chances of pregnancy are less.
If seminal fluid was Inseminated in the vagina and if you were in ovulatory period during that time, the possibility of pregnancy is there.
Usually pregnancy symptoms won't occur immediately after intercourse.
The other possible causes for your symptoms are:
- Pelvic inflammatory disease
- Urinary tract infection
These two can also presents with symptoms like pain abdomen, nausea, urgeny of micturition etc.
So if the symptoms persist, better to consult gynecologist once and get examined.
Take care.

hello mam!
no worries i will help you
First you need to answer my few questions?
-is your menstrual ccycle regular?
-the day when u had sex what day was it count from the first day of your last menses.(if it was in between day 11 to 17 of LMP then chances of pregnancy are high).
-have you passed your expected date to menstruate?
-if its 33 days and onwards you can confirm it by strip test. i will cost you a buck.

Mean while if you are worried and afraid to consult any one

just get a drug available as named "PLAN-B" would be effective if used with in 72 to 98 hours of sex.
if passed that time no worries.
we will sort things out.
i would recommend to inform your parents they will take you to the doctor as your health and safety id their first priority. Dont let your fear take you to ill expertise and black abortion. you will suffer and repent for your whole life. trust me. it wil be all right.

@) above was just a possibility with worst case scenario.
it could be a simple UTI as sex predisposes to it. DO urine Routine exam and you will know. all symptoms are explained in that way too. is there any discharge coming out of your vagina? get metronidazole twice a day for 7 days . use topical clotrimazole and use a Biomousse gel as a shampoo and rinse it for at least 5 minutes. you will be fine

i will pray for you and will be here for you if you need me
