You are 239 days into a 280-day pregnancy, so there are 41 days — 5 weeks and 6 days — left until you reach 40 weeks. Bear in mind that the due date is an estimate: only about 1 in 20 babies is born on it, and most arrive within two weeks on either side.
Next milestone: 20 days until early term (37 weeks 0 days).
Months of pregnancy are counted in uneven buckets of 4 to 5 weeks, arranged so that the full 40 weeks fits into 9 calendar months. Week 34 sits inside month 8, and it stays there for all seven days of the week — so 34 weeks 0 days and 34 weeks 1 day are both "8 months pregnant".
If you want the strict calendar answer instead, divide by the real length of a month rather than by four: 239 days ÷ 30.4375 days per month = 7.9 calendar months. That figure drifts from the bucket-based month number, which is exactly why your care team sticks to weeks and days.
The days part matters clinically even when the month doesn't. Screening windows, term definitions and induction timing are all set by exact week and day — full term starts at 39 weeks 0 days, not "9 months". See the full weeks to months chart for every week.
The lungs are maturing well — most babies born from this week onward do very well with little or no extra support.

At 34 weeks 1 day pregnant you are about 8 months pregnant — day 239 of your pregnancy, in month 8 and your third trimester. Months of pregnancy are counted as uneven 4–5 week buckets so the full 40 weeks fits into 9 calendar months, which is why the extra 1 day doesn't change your month number.
"34+1" is the shorthand your midwife or doctor uses for 34 weeks 1 day — the number before the plus is completed weeks, the number after it is completed days into the current week. You may also see it written 34w1d. Both mean exactly the same thing.
34 weeks 1 day is 239 days, counted from the first day of your last menstrual period (34 × 7 = 238, plus 1). That leaves 41 days — 5 weeks and 6 days — until the 40-week mark.
About 5 weeks and 6 days until 40 weeks. Only about 1 in 20 babies arrives exactly on the estimated due date, though — most are born within two weeks on either side of it.
34 weeks 1 day is in the third trimester, which runs from 28 weeks 0 days until birth. Full term begins at 39 weeks 0 days.
