Hello,
First of all it needs to be confirmed whether the bleeding that you had in May was menstrual bleeding or miscarriage bleeding. You can confirm it by getting your HCG levels checked. In case of pregnancy loss, the value of HCG will return to a non-pregnant range(<5 mIU /L) about 4 - 6 weeks after a pregnancy loss. Other method of confirming whether you had a miscarriage is by getting ultrasound uterus done. This will differentiate the cause of this bleeding as bleeding due to pregnancy loss or menstrual bleeding. Since you had protected sex In may, hence that would not have resulted in pregnancy.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
