4 months postpartum and bleed


I gave birth to my son 4 months ago and got the depo shot for birth control but haven’t followed up to get another one. Well recently I’ve been feeling like I’m pregnant! The other day i was nauseated, I’ve been super tired but idk if it from lack of sleep cause my son hasn’t been sleep straight through the night. Also I’ve been having weird feelings in my tummy? And this dull headache that won’t go away and today I got that bright red spitting like implantation bleeding🤦🏻‍♀️ I’m gonna take a pregnancy test soon but I just need so reassurance or idk. I really hope I’m not pregnant again, I’m not ready yet ☹️ and recently before all this me and my husband relationship has been so rocky. Someone please tell this doesn’t sound like I’m pregnant AGAIN!
