Hi, Welcome to Health care magic forum.
The presence of cramps, light headedness,
dizziness, may present during early
pregnancy, but its presence may not suggest the pregnancy.
You had unprotected sex at the end of the deposhot, then you had period, then you had sex, so it may not be the pregnancy. Any how to exclude the pregnancy, you can have home pregnancy test.
Take more of green leafy vegetables, pulses, sprouts, and protein rich foods to have blood, good health and resistance.
wishing for a quick and complete recovery. Thank you.
