Faint control line, dark test line, first response

Mern

Hi I’m posting I’m this group too I’m pretty sure I conceived beg of Dec (took morning after pill but for sure was ovulating), missed my Dec period- but haven’t had my period since mid Nov. this app says I’d be due in Aug

Anyways, the control line is super faint and test line is dark. Never happened with my other kids. What could that mean? A lot of HCG? Maybe multiples? Idk???
