I had unprotected sex on 2/3 June took morning after on 4th, due to ovulate on 6th, had sex again on 9th and 16th June. Now spotting pinkish stuff, and lower back pain, cramps, headache, dizzy, nausea, tiredness sensitive breasts. Period due on 24th June. Could I be pregnant

I think its just the side effect of the morning after, but it will stop after you got your period, but better to have a home pregnancy test, its 10-15 days after the first day you missed your period.
