Hi,
It's natural to be tense ,when one has multiple symptoms like you have!
- An acute illness causes
hormonal imbalance & so irregulararity in menses, breast tenderness can be explained
- With the oral contraceptives(if taken without break),& additional condom,I think there is less possibility of
pregnancy.Precum rarely contains sperm. But if you are not sure of regularity of oral
contraception, go for blood HCG test to exclude pregnancy.
_Lac of appetite,nausea,bloatedness you have is due to the infection/antibiotics causing
hyperacidity .
_ the pain in lower abdomen/
backache is a common symptom of UTI/ cystitis/lithiasis.( calculus)
You are advised to get investigated as per your doctor's advice , to be assured & get treatment needed.
Thanks
