So I think I might be pregnant but there’s a couple problems I have no idea when I could of conceived the baby and idk if I’m pregnant sooo I’ve took home pregnancy test some are negative some are postive! Took a blood test it is negative but my period is late! I already have 4 kids so me and my husband hardly have time to do it or time alone. Last time I can remember sex is beginning of Jan but I had my period Jan 17th but it was a short period. What do I do? 2 of the tests I took below
