First OB Visit

Mary

So this is month 8 of my husband and me TTC. I got a new job last week and they have a 90 day waiting period for health insurance. My insurance from my old job will end next month, leaving me without insurance until the second week of June. My question is how long after finding out I’m pregnant can I wait to go to my first OB appointment? If I do get pregnant this month and wait until my insurance kicks in I’ll be about 13 weeks until I go. Is that okay or do I need to take preventative measures this month?
