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, but "not pregnant" on the clearblue digital. Hoping this is a new pregnancy as we are actively ttc again.
