Hi
Dr. Purushottam welcomes you to HCM virtual clinic!
Thanks for consulting at my virtual clinic. I have carefully gone through your query, and I think I have understood your concern. I will try to address your medical concerns and would suggest you the best of the available treatment options.
As your urine test is negative , you have very minimal chances of 
pregnancy.Please continue your doses of 
Primolut N. You will get your periods within 3 to 10 days after finishing tablets.
If you have any doubts , blood 
beta HCG and USG can be helpful.
In absence of pregnancy, pregnancy like symptoms may be due to PMS- 
premenstrual syndrome. I will suggest use of B LONG F, EVION, PRIMOSA one each daily for 3 months.I will suggest indulging in a healthy diet and regular exercise regime.
Include plenty of fruits, salads, vegetables in the diet.
 Have adequate water intake , say 8 – 10 glasses per day.
 Avoid deep fried foods, bakery products, and refined sugars.
Avoid 
substance abuse, if any.
I hope my answer helps you.
Thanks.
Wish you great health.
Dr Purushottam S Neurgaonkar
