VVVFL for 3 days now, should I be worried?

Holly

Sorry guys I know I've made a thousand posts this cycle, but when things change I want to get opinions. My worry right now is that I am 13dpo and I've been getting vvvfl for the past 3 days. it's not getting any darker. Temps look great in my opinion, but I had a chemical last month and also got very faint lines for 3 days then started bleeding. The difference I've noticed is last month my temps were gradually decreasing each day before AF came, currently with new chart they've gradually increased each day since the positive so that makes me feel a little better. Last month I had severe cramping from the first day of bfp. this time no severe cramping. BUT I am so so worried it will end bad like last time because the lines are not darker. See pic below of bbt chart and tests (oldest test pictured first). What are your thoughts? Curious to know if anybody has had similar situation and everything ended up fine. Thank you in advance!! :(

Clear blue is obviously not as sensitive,

but these were both this morning at 13dpo
