Hey y'all. I've been really bad at taking my birth control recently especially considering I've been trying to stack. So inevitably after starting this most recent month's pills I started spotting. I hate spotting so I just decided to have a withdrawal to get it all out of the way. And here's where my question comes in. I'm driving up to Boston to visit my (let's just make it easier and call him my) boyfriend on Thursday, and I'm only on day 4 of my withdrawal. I think I'm going to begin taking pills again tomorrow (giving myself a 4 day like with Yaz etc) so that I'll stop bleeding by the time I leave. That gives me Mon, Tues, Wed, and Thurs to take pills to get myself protected again. We will definitely have sex on Thursday. I'm pretty sure I'll be fairly well protected after 4 days so that we won't have to worry about backups. Yes/no?
ETA: I know the 21/7 rule. I'm curious as to how protected I am from pregnancy by 4 days of pills, with the full intention of taking the remaining 17.
