Hi guys... may I ask your opinion about this matter.? Last June I got a surgery which is ASD closure. it's a opened heart surgery.. Then during upon my confinement at the Hospital. Where after the surgery I have a menstration. Then after my confinement I got discharged from the hospital and continue my recovery period at the house. And then, i expected to have my menstration this month of july. And I already count it from the calendar and I found it late. I am delayed for almost 3 days from now. Where in I started to think, I never had sex with my partner for the whole month of june until now because, I'm still in the period of recovery from the surgery. And my menstration is regular. so, how come I got delayed this July? What shall I do? I began to get paranoid.. Could you please somebody there help me to my problem? I appreciate your advices.
