OK, i am new to this and mistakenly posted my question/concern in the wrong community. lol anywho , For five days i had expiernced some spotting. I know, spotting... no big deal right? wrong ..lol the first two days were the light pink discharge, the third day was a bright red discharge. this particular day the discharge appeared to be a little bit stringy and when i touched it it was sticky. the last two days were brown discharge. the day after i had stopped spotting the left side of my uterus started to throb. not for long ,maybe a minute or two and it came and went as it pleased. later on that evening it happened on my right side. For about a week I have had some discomfort in my lower back but nothing too bad. Last night I did have sex but during my belly felt heavy and afterwards i did have pink spotting. Now I did take a pregnancy test but that was before all this mass confusion going on in my head...so about two weeks ago and that was a BFN. Menstrual wise they are irregular however they are always heavy and last 7-8 days. I don't know if this is something normal or if i could be having early pregnancy symptoms and should retest or whats going on. Has anyone else gone through this?
