Thanks for your query
If the pregnancy
test is negative, then chances of your being pregnant are not good.
There are very rare situations where this test is falsely negative.
Moreover, merely relying on cervical mucus for ovulation is not a good way of trying to conceive
If you are anxious to conceive, please see a proper infertility
specialist, get yourself investigated accordingly and then proceed
Also, I hope you had good follow up after your miscarriage
, since bleeding for more than 3 months is not normal
