Bbt lower but no period

[Sanlin1990]

Hi!
im charting my bbt and im currently 13dpo and usually my period starts at 11 dpo, at 11 dpo i had a dip in my bbt with quite bad cramping but 12 dpo my temp got up a little and today down again, still no period, no period feelings but my boobs start to feel full and a bit tender and i had a bit off nosebleed this morning, very mild cramping comes and goes and i started having heart burn today usually that comes early after ovulation but not this time.
I also had a good feeling of geting pregnant this cycle it really felt like this was the one but now everything feels off.
can i still be pregnant even tho my temp is low and i haven’t had a positive test yet? Could it have been implantation cd 41/11dpo?

This might sound like an obvious question but at 13dpo and a late period, why haven’t u tested yet? I’d say you could of implanted 7dpo, do a test 🤞✨✨✨ good luck girl, I hope this is your month

Oups! I forgot to say that i’ve tested every day since 7 dpo with negatives :(

Ah ok, I don’t know then, I’m sorry.. hopefully you get an answer one way or another soon, I know how frustrating this can be😭✨

I got these tests today the upper one reads from 25 and the lower one from 10, feels like i see something.
