Hi,
Thanks for posting in HCM.
I understand your concern.
Frequent urination may not be always associated as a symptoms for
pregnancy. Generally it occurs little later part of pregnancy due to pressure symptoms and not as early as when you have conceived.
Frequent urination could be due to
urinary tract infection or
urethral irritation due to inflammation as the history says you had intercourse multiple times recently.
You say you have practised withdrawal method during intercourse. But this pull out method does not ensure protection as chances of pregnancy is higher as compared to other methods, since
pre-ejaculate fluid also contains active sperms.
Kindly wait for periods to happen this time, which would tell that you are not pregnant.
In case it doesn't, get your urine tested for pregnancy and consult Gynecologist for proper evaluation and management.
Hope the information provided would be helpful.
All the best.
