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
pregnancy test reports are negative, you can assume that you are not pregnant.
In case of doubt blood
beta HCG test and USG will be of help
With your history of regular cycles, day 10 to 20 of the cycle is the most fertile period of cycle. It will be a good habit of using barrier
contraceptive method like condom , if you have sex act in these days. This help you to prevent any unwanted pregnancy and STDs.
3 ) I will suggest you to get USG done to know as to why you are passing clots during periods. As this is considered as heavy bleeding. I will suggest you to use Tab
Pause MF 3 times a day for 3 days or as needed to control the bleeding.
I hope this answer helps you.
Thanks.
Dr. Purushottam Neurgaonkar .
