Hi there, I have understood your concern. I will suggest you the best possible treatment options.
1 ) First of all do not panic.
2 ) As your urine and blood tests are negative, you can very well assume that you are not pregnant.
3 ) The unusual discharge that you are getting can be due to delayed onset of periods.
I will suggest you to simply wait for the onset of periods.
4 ) As you are trying for
pregnancy, I will suggest you to opt for a healthy diet and regular exercise regimen. Include more portions of fruits, salads and vegetables in daily diet. Avoid deep fried foods, bakery products and refined sugars. Use of vitamin B 12, Foloc acid and Omega 3 supplements on daily basis at least for 3 months before you plan to get pregnant. This will help to prevent various complications during the pregnancy and delivery.
I hope this answer helps you.
Thanks.
Dr. Purushottam Neurgaonkar.
