only 2 weeks till my contraceptive injection runs out, i have only been on it since august will this make any difference to how long i will need to wait? My daughter is 3 and i was on the injection for a few months after i had her before switching to cerezette which i then switched back on the injection due to cerezetter making me bleed for 3 weeks at a time then not at all for months. this fortnight is dragging so much!!
