Welcome to the forum,
Its nice to know that you want to conceive. Decrease in flow during periods can occur due to stress and anxiety, low Hb% in blood, hormonal
, etc. Sometimes due to pregnancy
. When HCG concentration is low in the urine, you may get false negative pregnancy test reports. You may see slight spotting too. Get clinically assesses or get a blood test
done to detect HCG levels in your blood.
If you get negative report, you may need HRT or ovulation study. You may have to go through USG, get your partner's semen analysis
Take food rich in iron, minerals, calcium, antioxidants. Keep yourself well hydrated. Do not take stress, avoid any type of addiction. Take care.
