Planned Csect @ 38 weeks.

Hi Mummies! Just wondering if it's too early for a csect to be done at 38 weeks? I'm just curious bcos my first pregnancy, I had to go thru emergency csect at 40 weeks as I wasn't dilating. Then for current pregnancy, I opted for csect straight - to eliminate the unnecessary like previous round. My gynae suggested at 38 weeks but I insisted on 39 weeks. However, I feel so heavy now, experiencing sharp pains at lower tummy and even mild contractions (my gynae is aware). Now on HL and idk if I can stay till 39 weeks like I chose before this. A part of me feels I'm not ready - seems too early. I'm currently at 35 weeks. Please share your thoughts. Thanks!
