Ok people, this is new to me. I'm 31 and Ttc. I had an IUD in for 3 years and for it removed beginning of March. I had a regular cycle which began April 1st. Starting this week, I've been exhausted and absolutely nauseous. I had to take off work today bc of how fatigued I was. I had sharp pain in my lower left abdomin on Tuesday. It's too early to test for pregnancy as in 8 days out from my next cycle. Any ideas? Could it be early signs or implantation?
