* You are on birth control pills- You had missed tabs in the cycle -but you say you had taken it the very next day morning.In this condition mostly you may not have conceived.
The frequency of urine can be due to cystitis-which needs treatment after investigations.the breast problems can be due to hafazard intake of pills.the upper vaginal swelling (as you say it)may be due to distended bladder.Your Dr will prescribe you antibiotic, alkalising syrup.& cystone
like Ayurvedic medicine as per need.
*The birth control pills are hormones,arranged to released in a way to skip ovulation & get vaginal bleeding in a cyclical way. for this, a regular consumption of pills is desired.Forgetting it once & suplimentation next day can be adjested.But repeated skippings may create imbalance of hormone OR- By chance,if you had forgotten to take missed pill -There is risk of conception.
I would advice to blood HCG
test done for ruling out pregnancy
(+ve 8 days of ovulation)at present OR urine preg. test 8-10 days of delayed periods.
You need to be careful in taking BC pills hense forth.
