Very late

Marne • I am 31 years old and we have been TTC for 7 months. So far I`ve had late periods, spotty ones. Still no PPT
I was ten days late with my period, never having a late period prior in my 31 years. With being that late I never had a positive pregnancy test which was very discouraging. With that being said I had nausea, food aversions, extremely tired, excessive use of the bathroom. All the signs were there. I even had implantation bleeding a few days after ovulation which would have been conception as well. No matter what the blood tests told me and the pregnancy tests told me I still felt very pregnant and my late period was just solidifying that for me. Then on the tenth day at night my period came. Now it's not a normal period mind you... Not as heavy as mine normally is so idk what to think, I am just sad over it and still don't understand my nausea or other symptoms as well. Thanks all for listening to my rant... I am just very confused by all of this and if anyone can offer any words of wisdom it would be greatly appreciated.
