Had 4 what seem like normal periods but still wonder if I am pregnant

Due to the fact that your periods have been on time, and you have had 4 of them, then I would say with 99% accuracy that you are not pregnant! Each month - with all the planets lined up, great circumstances - you have only a 25% chance of becoming pregnant. Thus doctors saying that most couples take upto a year to get pregnant - and IF there are any problems those will be more investigated if you have tried that long! most women ovulate 14 days before the date of their next expected period. So i tell women to start having sex - with help - 2 days before through the time and 2 days after - like a good week in total for sure! The help part is placing pillows underneath your buttocks during the entire time and as long as possible after. You can help nature out with gravity and entrapping as much sperm as possible! Also take prenatal vitamins - the actual prenatal ones (they have the right mixture) these hve been shown to increase your fertility - greatly - and also helps the baby's development! Good luck honey!
