Help me please

Samantha • Had our first in November 2015, our second in December 2016, now thanks to and IUD failure we are currently pregnant with our 3rd and couldn't be happier. Maybe I'll finally get a girl.

Ok ladies I dont know what to think. I ovulated on the 20th. Well my timing was perfect, and got down to it when we needed to. Well I'm breastfeeding my 1 year old so I'm running a little irregular. But my OPK gave me the proper timing and my temp rise confirmed. Well my period was due Monday and it started with spotting then went dark early the next morning. Well I have a few faint lines on tests leading up to my period. Well my period is almost gone and it's been really weird. I have also continued having nausea and tiredness. Which is just odd. Now the only time I have ever felt like this is when I was pregnant. I took a test this am and there is a second line it's light but darker then it was before. I don't know what to think.
