Hi there, I have understood your concern. I will suggest you the best possible treatment options.
First of all do not panic.
The very first and important sign of
pregnancy is a missing periods.
If she has regular cycles, and you have had unprotected sex act in the fertile period of cycle, means between day 10 to 20 of the cycle, then she can get pregnant.
To confirm your doubt, please get morning's first sample of urine tested for pregnancy, if she has missed her periods.
In case of doubt, blood
beta HCG test and USG will be of help.
All the symptoms that you are telling can be due to pregnancy, only if she has a missed period and positive urine pregnancy test.
If the test is negative, then her symptoms can be due to PMS -
premenstrual syndrome. In that case I will suggest to indulge in a healthy diet and regular exercise regimen. Start with long acting form of Vitamin B 6,
vitamin E and evening primrose oil supplements on daily basis at least for next 3 months.
I hope this answer helps you.
Thanks.
Dr. Purushottam Neurgaonkar
