off depo 12 months ago - would this affect my fertiity?

Hi,
Welcome to ehealthforum,
After stopping with the birth control use, your normal fertility can return back within few months to 1 year’s time. Consider monitoring cervical mucus changes and the BBT (basal body temperature) charting to predict your ovulation and time your intercourse for having fruitful results. Have diet with foods rich in zinc content to ensure better maturation of egg and sperms.
Do not delay in confirming pregnancy by getting HCG levels tested if you suspect chances of pregnancy. Also consider requesting your gynecologist/obstetrician for getting serial HCG levels tested. Doubling up of the hormone levels in 48-72 hours will show that pregnancy is going on smoothly. If levels are not adequate, then external hormonal supplements (progesterone or HCG injections along with aspirin) should be considered to be started to help with preventing miscarriage/threatened abortion. Take adequate rest. Drink plenty of water. Maintain healthy diet. Avoid any heavy work. Avoid having intercourse during first trimester (especially if you have had early pregnancy loss before). Avoid lifting heavy objects and climbing stairs or standing for long periods of time. Look out for danger signs like spotting, increasing intensity of abdominal cramps and back pain etc and report any unusual/abnormal/new symptoms immediately to your gynecologist/obstetrician. All the best.
Take care.
