If you believe that you could be preg. go get blood work done! But I know if you think you are preg. you will make yourself have the symptoms!! Well good luck and hope you get your good news.
I am having the same problem I had my last period on May 7th and I have taken like 3 pregnancy test in the past week and all have came back negative. I had a natural miscarriage on March 2nd and my May 7th was my first period after the miscarriage because I didn't have on in May. I am not having any symptoms besides being tired and having headaches. My last pregnancy when i had the miscarriage; the symptoms were very obvious. I had swollen breasts, fatigue and a decreased appetite. I don't know what to think, I hope it is nothing serious, if you find out anything let me know please! Thanks
