Please help! Need advise!

Hello ladies! Im new here and not sure if im posting in the right spot but anyways. My husband and I have been trying to conceieve for the past couple months after losing our first son in stillbirth June 2017. I had my lmp on Jan 11-17. On January 27th i started spotting a very light pink not enough to fill a pad up though. Then around the 29th it got a dark red and then straight to brown. Now since yesterday its been brown then light pink then back to brown. My regular periods are usually medium flow with clots constant dark red. I havent had a single clot since ive started bleeding. I have cramps every now and then around both overies. My breats have been sore and look a lot fuller. Im constantly nauseous. Been having hot flashes (which i never get on a regular period). i have backaches, sore breast, mood swings,etc. Has anyone else have this experience? If so what was it for you?
