While on loestrin 24 fe my girlfriend have missed 4 period.?

she has taken two pregnancy tryout but the both came out denial. could she still be pregnant? get a doctor pregnancy theory test done that will be the easiest and best way to speak about
two years ago my best friend didn't have her time of year for about 6 months and be never pregnant.it can be the medicine she's taking, don't verbs. just for right in a minute wear one of those extra spermicide condoms by trojan to be on the safe side. my girlfriend have always struggled near her periods because of her anxiety problems. so approaching i said before, it can be the drug, it can be more of an anxiety problem ESPECIALLY when you guys are dealing with this. but since that's approaching..a birth control med, right? it may just be the nice that lowers how many times a girl get her period surrounded by a year...just stir to the doctors asap.
