Hi my name is Hannah me and my husband have been having unprotected sex for about less then a year. Because we are anxious to have a baby I keep sycing my self out thinking im pregnant. So we started using this app called my days and I have been keeping all of my info on it when we have sex when I start and finish my period everything but I also dont know much about ovulation the only thing that I know about ovulation is that woman have it. But by using the my days app we have been making sure we have sex when the app says im on high fertility and when it says im ovulating but who knows if it works.... But anyways my symtims are I have been burping alot and im not sure but almost feels like im getting heart burn. last night at 8pm i started to get really bad pains in my stomach and felt like i needed to throw up but never would i eventually tried making my self throw up because it hurt so badly but I have a really strong stomach and wouldnt let me throw it up. i went to bed and woke up at midnight with more pains and so i got up and took a bath after the bath i finally threw up around 1:14 am (but i also started my period on the 12 andit is now the 14 but it was lighter then my periods have ever been) could i be pregnant or am I sycing my self out again?
