I have hella anxiety and need advice

So my periods have always been very irregular since I started in middle school. Jan 2021 I got the pill to regulate them and it worked for 6 months until I stopped bc I saw weight gain. But ab a month ago I started them back up daily not missing a day. I’ve had unprotected twice and haven’t bled yet. He pulled out and even needed another minute to finish after pulling out too. This isn’t abnormal for me but bad timing. Ik the precum but if it comes right before actual semen, like I said he was out and needed another minute. Someone tell me I’m just worrying too much please.
