Me and my husband have been tryin to have a baby for 6 months now. My last period was July 20. I estimated my ovulation for Aug3. Today I am 12 DPO and yesterday I had VERY bad BAD cramps. They lasted a few hours but NO spotting. Well last night I had LIGHT pink VERY little spotting. It lasted all day today also. I am wondering if this is implantation bleeding/cramping because Im not suppose to start until Monday (3 more days) and I NEVER cramp except the day I start and the day I end. Also today I had a weird kind of cramp (kind of like your side hurting) except it was in my LOWER stomach almost in my pubic area. Im not sure what that Pain was. I am still light pink (sometimes brown) spotting but NOTHING to even wear a panty liner over.
