I had an outer course on 18 feb and I checked for hcg blood test after 30 days it was negative. After that I didn't have any intercourse. I am getting periods but it lasts only for 5 days and the flow has also decreased. However in between the month of April -May I felt dizzy and had nausea. Moreover I feel bloated and my stomach pain. Recently, I had a sharp tingling pain on the right side of my breast and had 3-4 hairs around the same area. I feel tired all the time. Am I pregnant or is it something like a surprise pregnancy??
