Ok so my hubby and I have been ttc for a few months. I have been getting AF on a regular basis but for about half a week ( last few months ). The last month or so I have been feeling different .... 
My belly is hard but still flabby( I'm not thin - I've got extra ... And put on weight lately but it's not all flabby its hard near my rib cage - it just feels different. 
I have had acid reflux( heart burn ) all day
I'm tired all the time and getting normal any of sleep... 
We have been ttc on the best possible day and the week around it. 
Am I just over reacting and being hopeful or do you think I could really  be pregnant?
