Hello, im just a bit concerened and was lookign for some advice, i had a baby almost 4 months ago, and i breast fed til 2 months, i got the depo injection at 6weeks, after she was born, i had an after birth period, then didnt have a period until last week. Which was very strange, it was heavy but a big amount for just the first 3 mornings, then barly any during the day/night. i then on the last 2 days it became very heavy.. I have had un protected sex since the injection.. and was wondering could i be pregnant?????? + tghe only symptons ive had are, ovarie pains. and a bit of weigh gain (which is all in the depo injection symptons)
