My cycle started September 16th it was 4 days long this month. I normallyhhave a 29 day cycle on September 23 we had an oopsie on cycle day 8.. 1 day before my online calender said was my fertile window. Then on September 30 my supposed ovulation day ( I did have bad cramps that day) we had sex two times using the pull out method and no he did not use the bathroom in between but we waited 45 minutes before ruound two is pregnancy possible?

No there time when your body going threw a change so your cycle change

Any time you have sex, pregnancy is possible.

Online calendars are a joke, they're for fun, not for accuracy. Unless you're tracking ovulation using basal temperature readings for at least 6 months, you won't know when you ovulated.

The pull out method isn't a method of birth control. It's what we lay people call "trying to conceive". There's more than enough sperm in pre-ejaculate (which makes his penis slippery enough to enter the vagina) to get you pregnant. So pulling out means nothing. You're having unprotected sex, which increases the chances of pregnancy.

Wait until your period is at least 2 weeks late, then test using first morning urine. If that test is negative, wait for you next period, and if you miss it, test again or get a blood test.

Use at least two forms of birth control, the best combo is the pill and a condom. But even then pregnancy is possible, just less likely than having unprotected sex/the pull out method.

Good luck.
