@Anniewayte91 yes one sides pain is likely the corpus luteum (cyst) that the egg came from. With regards to CM it wasn’t reliable to track for me as it changed every month in the tww when I wasn’t pregnant. These were my early signs.
Early Symptoms
5DPO:
Weird tummy muscle spasms I could see my tummy moving below my belly button & to the right. Sharp shooting pain in same place woke me up in the night.
6DPO:
11am had lots of stabbing shooting pains in lower abdomen.
9DPO:
Bit constipated. Very vivid dream.
10DPO:
Very bloated. Very vivid dream.
11DPO:
Boobs feel a tiny bit tender if I push them. Got that low down AF ache feeling. Got that same twitch feeling in the same place & had shooting pains on knicker line.
12DPO:
Achey tummy down low. Ovary twinges. Lots of cramps down low. Some muscle spasms in upper abdomen. Tender nipples but not at bad as ovulation time. Lots of gassy bubbles in tummy & wind. Diarrhea.
13DPO:
Boobs hurt in the middle when I push them. Muscle spasms just below ribs & loads of twinges & cramps down low. Bit of diarrhoea.
14DPO:
Tummy muscles feel pulled when I stretch up. Feel like I have stitch.
15DPO:
Tested positive after missed period.
Notes:
*I didn’t notice any difference in my CM to any of the 3 previous months I was tracking it.
*I didn’t get any implantation bleeding
Hope this helps x
