Health One Insurance

We have to be covered by a pre-existing pregnancy, if I leave a job with health insurance and go to another job?
I've been looking for work over the past 3 months and now that I finally have an offer, and want a response from me within a few days …. I think I might be pregnant. Can anyone tell me what ramifications if I accept my new position as far as referring to health insurance. Will I be able to be covered by pre-motherhood with a current case? Do you know if Cobra covers pre-existing pregnancy?
I was 6 months pregnant when I started my new job and I was covered. His work encompasses not actually leave the communications Initial national health. The incs covers the birth and hospital stay.
