TTC after being on Depo for half a year and the pill for a year!!

Hi ladies, I quit my BC in early October, I didn’t ovulate in October but had breakthrough bleeding a couple days after stopping the pills. I ovulated in November and also this month too, I feel so discouraged...I just want to get my BFP already. Could me being on the depo in the past then switching to the pill right after be messing with my fertility? I know I haven’t been trying long at all even though it’s only been 2 months, but it’s hard to stay positive. I’ve tracked with OPKS for the last two cycles, nothing yet. If I’m not pregnant this cycle I’m planning on buying Preseed! Comment with advice if you’d like!
