Hi Everyone!

I am 4 dpo which was charted on glow to be the 11th but I believe my chart is off. My max cm was on the 7th. My husband and I had sex on the 7th and every other day beforehand. On the 8th I started having awful stomach pains when I was trying to fall asleep. I never got sick but it was a hunched over nausea/ cramping pain. This was 3 nights in a row. I still get small cramps but nothing major. Then I started having awful sulfur smelling gas come out of me all day. I have no appetite but I feel bloated and I think I look bloated. I've had headaches the last two days that were awful. My nose has been running yet at other times is stuffed. Yesterday I started to feel exhausted and it seems that I'm more tired everyday. I literally feel no energy to do anything. Could these be signs of pregnancy??? Any comments or advice are much appreciated! Thank you all!
