faint lines

Hi ladies, i had a miscarriage 4 weeks ago at 8 weeks and 5days pregnant. i havr been taking hpt/hcg tests and they have been negative. However a week ago i ovulated, confirmed with clearblue tests, cm and ovulation symptoms... my husband and i bd'd twice during the fertile week and this week i've been experiencing all of my pregnancy symptoms and received faint positives on the frer tests. Hoping this is a new pregnancy as we are actively ttc again.
