Because that means my body is working again! Had a depo shot in June, should have had 2nd one early Sept but we decided we wanted to start trying. Been waitin for the ever since! Took a couple months, so I guess I'm one of the lucky ones since I've seen tons post that it took 6+ months for her to rear her ugly head. Told my OH I'm glad she's here but I DON'T wanna see her again for 10 more months! It's pretty light compared to my normal day 1 & 2 but that's ok...the important thing is that she showed!
