Ovulation predictor off and overweight

Hey y'all. I'm currently almost 22 (14 days shy) and I'm married to a sailor. My husband and I have been married for 6 months and we have considered trying. During my predicted ovulation time frame I showed no signs of ovulation. I didn't have CM, I wasn't in the mood, I showed no pain, I felt totally normal. Now, almost a week later I'm starting to show some heavy CM, I'm in the mood constantly, and I've had mild back pain. My husband and I have sex and don't use any form of protection. My period is estimated in a couple days and I just wanted to know the possibility that I could get pregnant. I didn't get ovulation predictor kits (which I plan on getting next month) but I felt like I wanted to trust my body's signals over an app. Can someone please tell me if there is a possibility that I could get pregnant from this or not? I didn't leave my legs up after sex, and I'm over weight which plays a huge factor. I've seen a doctor and they say I'm totally healthy. Someone please share some advice :)
