Extremely long cycle

[Brown Eyed Gurl]

I'm am currently on CD 51 and as of last Wednesday still getting BFN on HPT.  Just wondering if it's possible to be preg. and still get BFN?  I have the same symptoms as when I was preg. b-4.  I MCed in Oct. and since then my cycles have been 32, 28, 34, 39 and now I don't think it's ever going to end.  I have a Dr . appt. next Monday but just wondering what else could be causing this if not preg.  I also had a neg. Beta a week and a half ago.  But with last preg..I was almost 8 weeks b-4 I got a BFP.

Thanks I have an appt. next monday and maybe I can figure what's going on. I'm 21 so I'll have them check for Ovulation.

Home pregnancy test are pretty good. In a 28 day cycle, and one misses their period, their bhcg is about 100, and most home pregnancy test pickup down to about 25. You could do a blood bhcg, very little false positive and false negatives. If you are over 35 I would get a CD 3 FSH or do a clomiphene citrate challenge test to evaluate Ovarian reserve/reproductive age. If under 35, test for proof of ovulation. Hope this helps.
