Sooo as of September I was like 103 days late, started on September 29th went to October 4th. Was supposed to get my period like October 14/15 but it never showed and now I’m like 21 days late. But I’ve struggled getting pregnant the last few years. But I have the very sore boobies and just wanna sleep/ feel like I’m just dragging my days along feeling… idk what to do I don’t want another negative… I’m also super emotional and I just want to cry…
