Help!

So me and my fiancé have officially said that we are now ‘trying’ for a baby ( we’ve been having unprotected sex for about two years now🤷🏽‍♀️) but haven’t wanted to put a stamp on it as we weren’t in a position to really try for a family.

So Around 6/7 days after ovulation I had some spotting for around 2 days - nothing major just really light pinky/light brown spotting.. me being me I of course googled this and was like ‘ omg okay so that’s gotta be implantation bleeding!!’ I took around 4 tests and all of them came back negative😓😓 the last test I took was around 3 days before my period was due.. I’m now 4 days late.

I’ve been having some really faint period like cramps and I’ve been feeling really sick - mainly in the morning or as soon as I’ve eaten, am I overthinking the whole spotting situation or do you think I should test again??🤷🏽‍♀️
