Some advice please (new to all of this)

Gemma
So I've been off BC since early July and had my last AF 15th -19th July. Glow said my peak was 28th but never took any OPK at all. Me and my fiancé BD twice during that day and on 30th so if anything did happen on my peak I would be 7DPO. (I know not entirely accurate)
Ever since Sunday I've felt so strange and my symptoms have just gotten worse over the last 4 days. I have the worse insomnia ever and I've been getting a pressure/pulling sensation in both side of my pelvic area.havent felt sick at all but have felt loss of appetite, bloating and had a slight spotting on Sunday afternoon but it wasn't anything like AF. Today I feel as though I've been hit by a bus!! My body aches and feels sore to touch and I have no energy what so ever. The sensations in my pelvic area have subsided but I've just been to the toilet and had what I can only describe as stringy egg white mucas with blood in it. It's not heavy at all and I have no other pains that would suggest it's my AF making an apparence. I've taken ovulation and it's negative so can't be ovulating pains and my AF is sheduled 12 Aug. Has anyone else had this?. It's making me so run down and I have no idea what to expect as we are TTC baby #1 so any advice from you mummy's out there would be much appreciated xxx
