I had my period from the first of the month until the 5, which was light but I got my depo shot on the 5th... Last week (one week after the shot) and I am having slight cramps and hard time eating some foods.... Could I be pregnant. I had sex on the 4,6 and 18th.... I have lost about 10 lbs in two weeks as well due to the fact that I have not been hungry and after I eat just alittle of something I get nausea and stop.....I have been tired too and aching joints.... Little scared and wonder when I should try and take a home test?! If I had a period for 5 days and off and on the 4th day but still on the 5th when I got the shot... My period stopped that day and normally does on depo. I dont have any periods.... Can anyone help me or offer some advice please!!!!!!
