Need some encouragement

I am new to this app. A little about me... I'm 41. I have 2 children 23(son) and 15(daughter). I had no problems getting pregnant either time. My daughter I conceived less than a year being off the depo, not trying, but not being the most cautious either. I got AF a few weeks after depo would have been due after being on it the 1st time for 5 years. I've been on the depo shot again for almost 15 years. My SO(he's 38) and I decided we wanted to ttc. I've been taking prenatals and drinking detox teas and taking liver cleanse pills for over a month now, just to start preparing My body for possible pregnancy. My depo is due tomorrow, but obviously skipping it. I bought a kit with LH and HCG tests. Just out if curiosity I used 1 of the LH tests last week and it was positive. I was thinking that was kind of crazy as the depo inhibits ovulation. Anyone in a similar situation? Just feeling like the odds may be stacked against us. Looking for some encouragement.
