Hi there, I will suggest you the best possible treatment options.
First of all do not panic.
As you have negative
pregnancy test results, you are most likely not pregnant.
In case of any doubt blood
beta HCG test and USG will be of help.
In your case, when you are having a missed period and urine pregnancy test is negative and there is history of bleeding with clots, it's possible that it was not a
miscarriage but delayed periods due to some kind of
hormonal changes. This mostly happens when the ovulation function of the ovary is not perfect.
Please seek good sex counseling advice, about whether you want to get pregnant or not.
I hope this answer helps you.
Thanks.
