### input:
my period started on 01 April 2010 and lasted 5 days. I had unprotected sex on 10 April 2010 and started feeling sick 3 days afterwards. For the past week, I have been feeling sleepy, very tired, lower abdominal pains, headaches, backache, leg cramps, a non-smelling egg-white like discharge which changed in texture to watery milky, but still not smelly. I thought I was pregnant, so i took a home pregnancy test on the afternoon of 20 April, it came out negative.  I took another one this morning, 21 April, it also came out negative.  Is it possible that i may have tested too soon? or is it possible that i may have contracted an STI? I still feel the pain on my lower abdomen, though its not as strongly as the first time i felt it.  Please help!

Hello dear, I understand your concern In my opinion it appears that the urine pregnancy test was done early. Usually the urine pregnancy test gives accurate results a week after missed period because Chat Doctor the hormone responsible for positive test starts appearing in urine around that time. And even the symptoms of pregnancy like nausea, vomitings, increased urination, sore breasts start 2 weeks after missed period. The first sign of pregnancy is missed period. So I suggest you to check for the period. In case if it is delayed go for a urine pregnancy test. It is too early to test for pregnancy and also to feel any pregnancy symptoms. As there is pain abdomen I suggest you to get physical examination done and also if needed ultrasound to rule out the cause for pain. There can be possibility of urine infection also. But chance of STD might be rare as you don't have any altered vaginal discharge and no lesion over genitalia. Anyway physical examination helps in accurate diagnosis so kindly consult doctor. Take adequate fluids up to 3 liters per day to prevent urinary tract infections. Avoid stress. Relax. Hope this helps. Best regards...
