Irregular Period After Miscarriage: Possible Pregnancy or Other Causes?

Question
Hi, I'm 32 years old, I have 3 children. In june last year I had a miscarriage . Today, March 2, 2205 I'm missing my period since Feb.22, my LMP was Jan. 25. I took 3 home pregnancy test and were negative,I also took a blood test which came out negative but, I'm having cramps, nauseas and feel very tired, sleepy and some days dizzy. I call my doctor today and I have to go to take another blood test.
My question is, according to the dates that I'm giving you, do you think that if I'm preganant it will come out positive, or should I wait? how long if necessary?

I will really appreciate your answer, I feel very disoriented even I'm a mother of 3.

Thanks,

Laura

Answer
If your last period started on January 25, then by now, a pregnancy test should be accurate. If the pregnancy tests have been negative, it is doubtful that you are pregnant, especially if they were blood tests. A sonogram may be useful if you have symptoms.
