Hi,
I guess your concern is could you be pregnant because of irregular light peroids,
nausea etc, the straight forward -could you be pregnant? -NO, NOT AT ALL.
Lets discuss with the information given by you:
1. You are on seasonale birth contro
2. You had PROTECTED SEX
3. GOT PERIOD this week 1+2+3=NOT AT ALL PREGNANT.
If a women gets her menses either on expected date or delayed date, that means she is not pregnant. Serial 1 and serial 2 info double protects from you being pregnant.
Still if you want to be sure, get urinary
pregnancy test done. These urinary pregnancy test kits are availabl at ur nearby medical shops at affordable prices. Buy it and do it yourself. If it is negative then you not pregnant, if positive then you are pregnant.
If the urinary pregnancy is positive, consult nearby gynecologist.
I hope this was informative enough, helpful and useful. Let me know if I can assist you further.
Regards,
Dr. Sudha Rani Panagar
