As I ovulate between Jan 31st to Feb6th, my husband and I have been trying to have as much sex as possible. We are trying to conceive. I was having a lot of sex before my predicted ovulation week. Today, I noticed a light green faint line under my belly button, and have been noticing some white stretch marks too. Is this a sign I could possibly be pregnant? I have been feeling a lot of lower back pain these past 2 weeks too so I’m not sure. No sign of nausea/vomiting yet as of now!
