 I've been trying to get pregnant for a year and a half now. I'm going on 5 days late tomorrow. I had horrible cramps or sharp pains in abdomen and pelvis today but Only discharge that was super light bloody tinged once and then the next time this and now nothing with major nausea for like 6 days and on and off slightly sore boobs and some gas . Took a dollar store pregnancy day after missed period and got a bfn. Can anyone give me their input. I thought maybe I have endometriosis cause I've tried chlomid, pre-seed and premama the last year and a half and nothing but now this is happening this time around when my period was due to start Dec 23rd. Now I'm also having pain on my lower left side near Pelvis so I'm so confused .
