Advice?

Hey ladies!

I am 21 on Lo-Orgestrel to regulate. I was supposed to start my new birth control pack 9/25 but didn't get to the pharmacy until 10/1. Had unprotected sex with hubby as normal and didn't really think anything of it because im irregular off of birth control and honestly don't think I can ovulate by myself. About a week after I picked up my bcp I woke up with a UTI and went to the doctors for a prescription later that day. Since then I've been sleeping more, with some bloating, but I've really noticed I burp and pass gas sooooo much now it's almost embarrassing. I've also had some minor back aches and cramps. Plus I've been really moody. I cried in the middle of Walmart because I felt like I was musty. All hubby could do was pull me in and tell me "Don't cry baby, I promise you don't stink." People we're looking at us like we were nuts. But what's really weird is hubby is acting different too. Taking 2-3 naps during the day and he is having cravings. For example, he couldn't choose between sweet and salty so he had Oreos and Milk with a side of hot cheetos. Now I'm wondering if my body tricked me and ovulated the week I missed and maybe I am pregnant. I truly don't want to give my hopes up. Especially after one miscarriage and no success after that. I find it so frustrating that other ladies my age can get pregnant on accident and for the life of me I can't do it on purpose.
