Thanks for writing to us.
The symptoms you are having are all non specific and do not conclusively indicate about pregnancy
Since your pregnancy test was negative on 7th april, uyou can do a repeat pregnancy test now to rule out the pregnancy. If the test is still negative then you need to consult your gynecologist who will prescribe you hormonal
tablets for withdrawal bleeding.
I hope this information has been both informative and helpful for you.
