Hello and welcome to HCM.
Thank you for your query.
I have gone through your query and shall try my best to help sort things out.
First of all, the symptoms you are experiencing are as a result of your hormones. Now whether these hormones are at a high because you just finished your period or because you are period cannot be accurately estimated yet.
I would like to know when exactly you took the 5 HPT's? You need to give at least a 2 week gap since the sexual contact to use the HPT, you could also get it checked on the first or second day of a missed period.
Another fact we need to shed light on, is whether your sexual contact was before the bleed you experienced (period) or after? If you experienced a period after your sexual contact, it clearly indicative of an absent pregnancy
Now, if you continue to experience these symptoms, it most probably has a hormonal
cause to it, and even if you do visit your doctor, he or she would ask you to wait it out.
For future reference I would like for you to know that a HPT should be conducted either 2 weeks after the sexual contact or on the first or second day of a missed period, with an early morning urine sample to yield a most accurate result.
I hope I have succeeded in providing the information you were looking for. Please feel free to write back to me for any further clarifications at: http://doctor.healthcaremagic.com/doctors/dr-shoaib-khan/64581 . I would gladly help you.
