Hi there, I have understood your concern and I will suggest you the best possible treatment options.
The most important sign of
pregnancy is a missing period.
If you have history of regular cycle and if you have crossed your expected date of menses and you are expecting pregnancy then I will suggest you to get morning's first sample of urine tested for pregnancy. in case of any doubt blood beta HCG test and USG will be of help.
Secondly, even if you are pregnant, then black coloured discharge needs to be investigated thoroughly.
If you are pregnant then USG will be definitely advisable.
This will help to know about the viability and
gestational age of the pregnancy.
Please seek prescription support from your treating doctor for antiemetic like
Doxylamine and
Folic acid and vitamin B 12 supplements and tablets of Natural micronized
Progesterone hormone, to support the pregnancy.
I hope this answer helps you.
Thanks.
Dr. Purushottam Neurgaonkar
