Hi, Thanks for using HCM.
test basically detects hormones which is excreted in urine. Blood HCG
test better than UPT. Use early morning urine sample for better results.
Delay in your period could due to stress
also as you had urinary infection.
If you are pregnant,since you were on antibiotic, need to know safety level of those medication in pregnancy.
Consult your doctor for examination and management.
Hope I answered your question. Feel free to ask me if you have any further queries.
Wish you good health. Take
