Hi welcome to Health care magic forum.
Your last menstual period was at the end of february. You are feeling all the symptoms of pregnancy
. It could be a pregnancy or pre menstrual symptoms, or any systemic infection.
I advise you to go for home pregnancy test, to confirm or exclude the pregnancy. If negative you can consult a physician.
If pregnancy is confirmed you can consult a gynaecologist for maintenance of pregnancy. If negative the doctor will get the blood H.C.G.test for confermation, you can have treatment for pre menstrual symptoms.
Wishing for a quick remission of symptoms, and thanks for calling, H.C.M.F.
