Hi, I had intercourse with a guy on the 15th day of february (last month) while on my periods (that started on 10th/11th). He pulled out before he could come. I took an emergency contraceptive pill on 16th (just to be safe), started noticing slight vaginal blood discharge/spotting around 22nd/23rd, and this has continued for about 10 days. Now the flow of blood discharge is heavier, more menstrual like, from around 3rd of march. Im not sure if this is still the pill s side effect/spotting or an early period or something else. Could I be pregnant? If so, when would be the right time to take a pregnancy test to confirm/check this?
