2nd spotting experiance.

Im 10 weeks pregnant today. Kagabe nag bleeding ako this is my 2 ndd spotting experience but this time hndi sya blant red its fresh red. no intercors for 3 weeks .. 1 weeks palang pinastop sa pampakapit na gamot. So wat i did. I went to the e.r as of my o.b and found out that it ng labas ng cervics ko is mej open daw but thank you Lord inside is close. They ran a blood test urine and another popsmire . sa blood and unrine negative for any bacteria nmn .. and mamaya daw will need mag pa ultrasound. For the headtbeat and all ung question is why nag spotting??
