Maybe pregnant?

SH
Hubby and I are TTC our rainbow baby. I miscarried in October, had a period in December, then were pretty diligent TTC on right days (BBT, CM) at end of Dec. I've been getting acupuncture since mid Dec too. My period has a long cycle sometimes (28-39 days). I'm on day 36. On Jan 8 i had some spotting and acupuncturist said i had a slippery pulse and was getting my period. I haven't bled since Saturday morning. Took a test today but it was negative. . . I think. Maybe a super faint line but u don't trust it. I'll try again in a couple days, but do you think i could be pregnant?!
