TTC and I'm confused this month

Celeste

Hi all, this is my first post and I am very new to all of this so please bear wit me🙏❤ Me and hubby have been TTC for 8 months now. Last month I got my period but it came 2 days late with spotting at first then into a heavy flow back into spotting. I never spot first, I get it full blown, heavy and it last for 7 days with most PMS symptoms. But it only lasted 5 and a half days. I then ovulated on the 28th of May and I had ovulation spotting which is normal for me but then the spotting lasted 4 days and then for 3 days I experienced heavy spotting (period-like almost) and back into 3 days of light spotting. My period was always regular. I have a 27day cycle with a 7 day period. During this time of spotting I had severe backache and a headache. I was supposed to get my period on the 11th of June and I am still waiting (so 5 days late). I have been feel nauseous daily since the 12th of June and a few days ago my breast got so sore to touch that it is still sore/very tender to touch. Today I have developed a severe headache with light headedness. I am so confused...that second spotting/bleeding threw me out completely. Anyone experienced this before? Your feedback would be greatly appreciated 🙏 ❤🙂
