TTC x 1 yr, faint positives then neg/bleeding.

1st faint positive (or of any kind) ever... Felt symptoms 5 days before AF, so tested many times over day or so. Sore boovs, to point I was sleeping in sports bra, amd it hurt to turn from side to side, heartburn, and CM white, creamy. Faint/moderate pos many times, then lighter on the days following. AF was due yesterday, and didn't come. Tested this AM, BFN. Assuming chemical. 😕 Haven't told hubs, as I had plans to suppose him with daddy announcement soon. Not sure whether to mention, as he may get even more discouraged than I with loss... how soon can we TTC again? When will symptoms go away? Do I need to go to doctor? Would have been 4 weeks 2 days today. + bleeding, mild brown mucus etc. today. Some cramping.
