PS You can test for pregnancy when your period is due or late, though First Response can detect pregnancy a few days before your missed period. Good luck! Let us know the result.
Well if you are ovulating then you're not pregnant.... yet. Yeast infection would result in a foul discharge, maybe even pain. The thing about yeast infection, though, is that some women do not even show symptoms and a lot of time it goes undetected and untreated. There are these new tests that you can buy at the drug store that can tell you if you do have a yeast infection or not.
Constipation is the infrequency of stools and they tend to be hard, round pebbles. If you're experiencing that is CAN be a sign of pregnancy as a hormone is released during pregnancy that relaxes the bowels making it more difficult to have a bowel movement. Drink more water!
First step I think would be to buy a box of yeast test strips AND a box of First Response pregnancy tests. You need to know if you are pregnant AND have a yeast infection as untreated infections can lead to problems. For constipation eat more fiber and drink tons of water.
