Going crazy

Bare with me, it’s a bit of a long one:

31 days into a 28 day cycle, think I O’d twice as had peak with ewcm on cd 13 and 17 with negative in between (tested cd17 because had sharp pinching pains with a big glob of thick blood stained mucus), bad cramping, nausea, BFN cheapie and cb, extremely emotional youngest child (unusual for her), right boob is aching and sore towards my armpit and pinching pain where my biggest fibroid is. I feel like I’m going to come on, but never had cramping this bad before without spotting and brown discharge before bleeding heavily (because of fibroids). Pregnancy is possible but it’s been months of trying and I thought my age was my nemesis as I’ve never had trouble conceiving before and I would have thought it would have shown on a test. So confused 🤦🏼‍♀️
