I ovulated on cd13 cos I checked the cervix, it was low,firm and close, dtd on cd12 cervix was very high and soft and 13 morning, tested urine hpt negative on dpo 11, on dpo16, I had twinges on the right lower abdomen, with cramps, spotted in the night with lower back pain like AF. Since yesterday, light bleeding with tinyy clots that just drop and dry off immediately. It is not consistent like AF, checked cervix, high firm and open to high firm and closed to low, firm and open. I'm confused, I am scared of doing a blood test cos I am really desperate to get pregnant. Pls advise me
