Yes absolutely, pregnancy can happen even the first time if its around the fertile days. First time does not mean safe time, thats a big myth. If pregnancy isnt planned, use protection.
Beta yes it is possible from the very first time, dont believe the safe-time talk. Whatever ur situation, if u have doubts or worries please talk to a doctor, they wont judge.
From what I read while planning, yes the body can conceive anytime around ovulation, first time or not. It really depends on timing in the cycle, not how many times.
Haan it is fully possible. There is no rule that first time cant cause pregnancy. If u want to avoid it, talk to a gynac about safe contraception options properly.
