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.
