4 weeks and spotting...

I dont understand why once i find out im pregnant... i start spotting.. its not alot but there's atleast 2-4 spots a day😭😭😭 i had 2 mc last yr and i just want to go thru a pregnancy without worrying... like today.. went to pee and when i wipe there was a light pinkish-brownish spot.. im not cramping but i dont understand why me.. this is how all my mc ended.. started with light spotting with cramps and eventually got heavier until i lost it... soo exhausted feeling this way.... i feel like i keep failing myself... my husband... my moms keeps calling but i havent been answering her calls lately.... i honestly have nothing wonderful to tell her... i dont know what to do anymore...
