I am 2dp5dt and really crampy tonight also feeling nauseous. I have been having headaches too. My <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> says I should be starting my period in like 2 days or so, the cramping is making me so worried that my period is going to start and this transfer will fail. I am taking estrace 2 times a day and pio shots at night. Has anyone experienced this before? Trying to stay positive but so worried.
