Is this okay?

I’ve been on birth control for about three weeks now and I’m supposed to take it at 3:50 I usually drink the b.c pill around that time like between 3:40-3:55 does it still work even though I’m drinking it a little around that time instead of exactly on that time? I’ve been having sex without condoms and I’m getting the implant in a couple weeks I just got to deal with the pills for now but I’m not really experienced on birth control pills. Thanks
