Stop the title pretty much sums it up. Ive been ttc since the beginning of January. I was ovulating april 16 and my period was supposed to come april 28 but it still hasn't come. I've taken two cheap tests and one first response test and all have come back negative. The 29 i felt like there was pressure on my cooch (like when you have a heavy period) and slight cramping but it only lasted a few hours. My boobs have been sore but i got a sunburn on then so i figured maybe that's why. Any comments anyone??
