30 weeks pregnant and I feel her head super super low

Gi

I just reached 30 weeks pregnant today, this is my 2nd child so I do have a bit experience but this time around it’s a little different and trickier. With my first daughter I didn’t start feeling Braxton hicks or her being so low until about 36+ weeks pregnant with this pregnancy Ive felt constant pressure since 28 weeks. Today felt super different I’ve been having constant discharge that looks watery and white and today I was super out of breath and can feel her head super low in my pelvic bone when I walk, when I sit, when I’m going up the stairs I definitely feel her head and my belly feels super tight all around especially at the top where she should be since I’m still so far from labor. Has anyone else experienced this and baby came super early? I’m pretty nervous and definitely not ready for her to come so early. Are there any precautions I should be taking? I have an ob appointment coming up soon but they are closed right now and I just want a little advice or tips from you mommas or nurses who are in this chat! Thank you so much for taking the time to read. God bless!💜
