I had a miscarriage in January of this year. My husband and I have recently started trying to conceive again. My period is >very< irregular, so it's hard to tell whether I'm late/on schedule/whatever. Today I noticed that I've had some brown, string-like discharge and some very faint but non-painful "cramping" in my lower abdomen (the only way I know to describe it is like rubber bands being stretched and then relaxing). As I said before, my period is irregular, so I'm not sure if these things are just a result of the irregularity or if I should try a home pregnancy test, and if so, when?
