me and my partner have been TTC for about 4 months now- although we haven't been using contraception for over a year. I had my last Depo Shot a year ago (I only ever had the one) and it took about 6 or so months for my period to return / regulate. my period has been regular for about 5 months now and we have been TTC for 4 months. I am pretty sure that I am ovulating regularly (I get pains etc) and we have sex on all the important days. I'm wondering whether it could be that depo is still in my system or whether this is normal and I shouldn't worry yet?
