Pink spotting for 2 days starting on day 9 of cycle and then on day 17 pinkish orange spotting that now is a lil more red than pink with lower back pain. i have 11 days before period is due, could i be pregnant?

Way too soon to tell: It can be hard to tell if a woman is pregnant because some of the symptoms seen in early pregnancy can also happen in non-pregnant women. A urine pregnancy test gives a reliable result if done correctly. One can test about 3 weeks after sex (3 weeks after when conception might have occurred), or 1 week after missing a period. An Ob-Gyn doctor can evaluate any persistent or worrisome symptoms.
