Had a little Scare last night 😰😖

Was in really bad pain last night. Felt sharp pain in my lower stomach. I told my boyfriend to take me to the hospital cause I didn’t know what was wrong. This is my first pregnancy so I’m new to all the pain and my body changing for the baby. I thought I was having a miscarriage even though I wasn’t bleeding I was just more worried that something was wrong with the baby. My job has been a little stressful and I don’t get enough rest from it. But long story short everything was ok the baby was doing fine I was just having normal pain . They say the baby is measuring 12 weeks and 4 days I thought I was 12 weeks and two days since my last appointment when I was around 8 weeks. But does that change my due date? My doctor told me I’m due Feb 15
