Help needed

Hi ladies so I recently had a baby (6months) but I am really really ill like I was at the start of my pregnancy last time. I am waking up hot I am drained am really tired feel sick but I keep feeling flutters in my stomach. I am normally a size 4/6 and I am so bloated I am now a size 8 in pants. I took a test this morning it said negative but before I did the clear blue test a negative line was already on this. I took this test yesterday my friend sees a faint line I don't but I am worried help please.
