38 weeks & FTM needs help!

I'm finally 38 weeks today & a FTM with a baby girl 💕 My cervix was 1 cm a week and half ago and thinning out. anyway, i had a headache for like literally 2 days and finally got rid of it until i woke up early this morning and been having contractions they were pretty steady too. I fell back asleep and now I feel very lightheaded and disoriented like. What's going on ?
