I signed up to this site in hopes that someone can help me or give me advice. The start of my last period was April 26th, 2017. It's now July 16th, 2017. If I don't get my period in the next 10 days, that will be my third missed period. This is very out of the ordinary for me as I usually have regular cycles. I saw a doctor about a month ago because I was wondering if I was pregnant (thought I could have concieved in early May) but had had a negative home pregnancy test. While at the Drs they had me take another urine test and it was also negative. She said there is no way I can be pregnant since the tests were negative and hCG would have showed up by that time. She told me to get in touch with her when I missed my third period. She said I have low progesterone and will need Provera to induce my period. However, I have been researching Provera and am concerned to take it because of all the side affects including birth defects in the first trimester. What if I am pregnant and hCG didn't show up in the test? I have read that this is the case for some women. Or what if I have conceived since I visited the Dr? I have been having some early pregnancy symptoms such as very sore breasts, back ache, very frequent urination, swollen feet, unexplained weight gain, etc. I am worried about taking Provera but also know that if I am not pregnant and just have low progesterone, then I need something to induce my period so that I don't have buildup which could lead to health problems. Any advice?? Thank you.
